Understanding this issue is crucial for Umbraco developers and content editors alike, ensuring seamless content creation and management within the Umbraco ecosystem. We will dissect the problem, offering insights into why this might be occurring and how to effectively address it. By the end of this article, you will have a thorough understanding of the Umbraco V16 preset value saving issue in compositions and the knowledge to implement solutions or workarounds.

Bug Summary

In Umbraco 16, preset values for fields within compositions are not saved when content is saved or published. This means that if you have a document type that includes compositions, and these compositions contain fields with default values, those values are not being persisted in the CMS. This can lead to unexpected behavior and data loss, as content editors might assume that the default values are automatically applied, but they are not.

This issue specifically affects fields that are part of compositions, which are reusable groups of properties that can be added to multiple document types. When a field is defined within a composition and has a preset value (e.g., a toggle set to "true" by default, or a slider with a default value of 0.5), this value should be automatically applied when a new content item is created using a document type that includes the composition. However, in Umbraco 16, this does not occur, and the fields are left with null values instead.

This bug can have significant implications for content management workflows. Content editors might need to manually set the values for these fields every time they create a new content item, which is time-consuming and prone to errors. Additionally, if the default values are critical for the functionality of the website (e.g., a toggle that controls the visibility of a section), the issue can lead to broken layouts or incorrect behavior. Therefore, it is essential to understand the root cause of this bug and find a solution to ensure that preset values are correctly saved in compositions.

Specifics

To provide a clearer picture of the issue, let's consider specific scenarios and examples. Imagine you have a website where certain sections need to be enabled by default. You create a composition with a toggle field set to "true" as the default value. You then include this composition in multiple document types. In Umbraco 16, when you create a new content item based on these document types, the toggle field within the composition will not be set to "true" automatically. Instead, it will be null, and you will need to manually enable it each time.

Another example involves a slider field used to control the intensity of a visual element on the page. You set the default value of the slider to 0.5, hoping that this will provide a balanced starting point. However, due to the bug, the slider value will not be saved as 0.5, and the visual element might not render correctly until the slider is manually adjusted. These scenarios highlight the practical challenges posed by this issue and emphasize the need for a reliable fix.

The inconsistency between expected and actual behavior can also lead to confusion and frustration among content editors. They might assume that the default values will be applied automatically, only to discover that the content is not behaving as expected. This can result in wasted time troubleshooting and correcting the issue. Therefore, it is crucial to address this bug promptly to ensure a smooth and efficient content management experience in Umbraco 16. The lack of preset values being saved not only affects the initial state of the content but can also impact the overall functionality and design of the website if not properly addressed.

Steps to Reproduce

To reproduce this bug in Umbraco 16, follow these steps:

1. Fresh Installation: Start with a fresh installation of Umbraco 16 to ensure no conflicts with existing configurations or packages.
2. Create Data Types:
   • Create a Toggle data type with a preset value set to "true" or "enabled". This toggle will serve as one of the fields within the composition and the document type.
   • Create a Slider data type with the following configurations:
     • Minimum value: 0
     • Maximum value: 1
     • Step value: 0.1
     • Starting/Preset value: 0.5 This slider will also be used within the composition and the document type.
3. Create a Composition:
   • Create a new composition. Compositions are reusable sets of properties that can be added to multiple document types.
   • Add the following fields to the composition, placing them within a tab named "Composition" for organizational purposes:
     • A Default toggle data type (the built-in toggle type).
     • The Custom created toggle with the default value set to true.
     • The Custom created slider with the configurations specified earlier.
4. Create a Document Type:
   • Create a new document type that is allowed to be created as a root node. This will allow you to create content based on this document type at the root level of your content tree.
   • Add the composition to the document type. This incorporates the fields defined in the composition into the document type.
   • Re-create the same exact fields as in the composition, but add them directly to the document type itself. Place these fields in a separately named tab (e.g., "Direct Fields") for ease of distinction. This will allow you to compare the behavior of fields within the composition versus fields added directly to the document type.
5. Create Content:
   • Create a content item based on the document type you just created.
   • Save and publish the content item without touching any of the inputs/fields. This is crucial to observe whether the preset values are being applied automatically.

By following these steps, you can reliably reproduce the bug where preset values in compositions are not saved in Umbraco 16. The next section will detail the expected and actual results, highlighting the discrepancy caused by the bug.

Expected Result

When following the steps to reproduce the bug, the expected result is that both the composition fields and the direct fields should inherit their preset values upon saving the content item. Specifically:

1. Composition Fields: The toggle field within the composition should be set to "true" or "enabled", reflecting its preset value. The slider field within the composition should be set to 0.5, matching its defined starting/preset value.
2. Direct Fields: Similarly, the toggle field added directly to the document type should be set to "true", and the slider field should be set to 0.5. This behavior is consistent with how preset values are expected to function in Umbraco.

In essence, the preset values should automatically populate the respective fields, ensuring that content editors have a consistent starting point and that default configurations are applied as intended. This behavior is critical for maintaining consistency across the website and reducing the manual effort required to set up new content items. The expectation is that Umbraco should handle the application of preset values seamlessly, regardless of whether the fields are part of a composition or directly added to the document type.

Actual Result

The actual result in Umbraco 16, when reproducing the bug, deviates significantly from the expected behavior. Here’s what you'll observe:

1. Direct Fields: The fields added directly to the document type correctly take their preset values. The toggle field will be set to "true", and the slider field will be set to 0.5, as expected.
2. Composition Fields: The fields within the composition, however, do not inherit their preset values. Instead, they remain null or at their default uninitialized state. This means the toggle field will not be set to "true", and the slider field will not be set to 0.5. These fields will effectively be empty until a content editor manually sets their values.

This discrepancy leads to a critical issue: the preset values defined within compositions are not being saved or applied when content is created. Consequently, the published content access (e.g., through the Delivery API) will reflect these null values, leading to incorrect behavior or missing configurations on the front end of the website. This can cause significant problems, especially if these preset values are crucial for the functionality or design of the website. For example, if a toggle field controls the visibility of a section, and it's not set to "true" by default, the section might not appear until the content editor manually enables it.

The fact that direct fields behave as expected while composition fields do not points to a specific issue in how Umbraco 16 handles preset values within compositions. This inconsistency can be confusing for content editors and developers alike, as it violates the principle of least astonishment. Understanding this actual result is crucial for diagnosing and addressing the bug effectively. In the following sections, we will discuss the implications of this bug and potential workarounds.

Implications of the Bug

The bug in Umbraco 16, where preset values in compositions are not saved, carries several significant implications for content management and website functionality. These implications can affect various aspects of the content creation process and the overall user experience.

1. Increased Manual Effort: Content editors are required to manually set the values for fields within compositions every time they create new content. This adds extra steps to the content creation process, making it more time-consuming and less efficient. Instead of relying on default values being automatically applied, editors must remember to configure each field, which can be tedious and prone to errors.
2. Potential for Errors: The manual configuration of fields increases the risk of human error. Content editors might forget to set certain values, leading to inconsistencies in content and potential functional issues on the website. This is particularly problematic when dealing with complex compositions that contain numerous fields with preset values.
3. Inconsistent Content: If preset values are not consistently applied, the website might display inconsistent content. For example, if a toggle field that controls the visibility of a section is not set to "true" by default, some pages might display the section while others do not. This inconsistency can confuse users and detract from the overall quality of the website.
4. Broken Functionality: In some cases, the missing preset values can lead to broken functionality. If a preset value is critical for the behavior of a particular feature, the feature might not work as expected until the value is manually set. This can result in a degraded user experience and potentially prevent users from accessing important content or features.
5. Data Integrity Issues: The lack of saved preset values can also lead to data integrity issues. If the preset values are intended to represent default configurations or settings, the absence of these values can result in incorrect data being stored in the CMS. This can have long-term consequences for reporting, analytics, and other data-driven processes.
6. Development Overhead: Developers might need to implement workarounds to address the bug, adding complexity to the codebase and increasing development overhead. This can delay project timelines and increase costs. Additionally, developers might need to spend time troubleshooting issues caused by the missing preset values, diverting their attention from other important tasks.

In summary, the bug in Umbraco 16 regarding preset values in compositions can have far-reaching consequences, impacting content creation efficiency, data integrity, website functionality, and development efforts. It is crucial to address this issue promptly to ensure a smooth and reliable content management experience.

Potential Workarounds

While a permanent fix for the Umbraco 16 preset value bug in compositions is awaited, several potential workarounds can mitigate the issue and ensure that content is displayed and functions as expected. These workarounds range from simple manual adjustments to more complex programmatic solutions.

1. Manual Setting of Values: The most straightforward workaround is to manually set the values for fields within compositions each time a new content item is created. While this is time-consuming and prone to errors, it ensures that the correct values are applied. Content editors should be trained to check and set these values as part of their content creation workflow. This method, however, is not ideal for large-scale content management or when dealing with numerous fields.
2. Content Editor Training and Checklists: To reduce the risk of errors when manually setting values, content editor training programs can be implemented. These programs should emphasize the importance of checking and setting preset values in compositions. Additionally, checklists can be provided to editors to ensure that all required fields are configured correctly before publishing content. This approach adds a layer of quality control to the content creation process.
3. Custom Property Editors: Creating custom property editors that handle the setting of default values can be a more robust solution. These custom editors can be designed to automatically apply preset values when a content item is created, eliminating the need for manual intervention. This approach requires development effort but can significantly improve the content creation experience.
4. Event Handlers: Umbraco event handlers can be used to programmatically set the values for fields within compositions when content is created or saved. By subscribing to events such as ContentService.Creating or ContentService.Saving, developers can inject the preset values into the content item before it is saved to the database. This approach provides a flexible and automated way to address the bug.
5. Scheduled Tasks or Background Processes: For existing content, a scheduled task or background process can be created to iterate through all content items and set the missing preset values. This can be particularly useful for websites with a large amount of content that needs to be updated. However, this approach requires careful planning and execution to avoid performance issues.
6. Pre-Value Editors: In some cases, using pre-value editors for data types within compositions can help mitigate the issue. Pre-value editors allow you to define a set of predefined values for a property, and these values can be set as default options. While this approach does not directly address the bug, it can provide a more user-friendly way to manage preset values.

Each of these workarounds has its own trade-offs in terms of complexity, effort, and effectiveness. The best approach will depend on the specific needs and resources of the project. It is crucial to carefully evaluate the available options and choose the one that provides the most practical and sustainable solution.

Conclusion
