To reproduce this bug, follow these steps:

  1. Fresh Installation: Begin with a fresh installation of Umbraco 16. This ensures that there are no conflicting configurations or existing issues that might interfere with the reproduction process. A clean environment is crucial for accurately identifying and addressing the bug.
  2. Create Data Types:
    • Toggle Type with Preset Value: Create a toggle data type and set its preset value to true or enabled. This toggle will be used to test the behavior of preset values within compositions.
    • Slider Type with Preset Value: 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 further demonstrate the issue with preset values in compositions.
  3. Create a Composition: Create a composition containing the following fields (add them to a "Composition" tab for organization):
    • Default Toggle Data Type: Use the default toggle data type provided by Umbraco.
    • Custom Created Toggle with Default True: Use the toggle data type you created in step 2, with the default value set to true. This will test if the custom toggle data type behaves as expected within the composition.
    • Custom Created Slider: Use the slider data type you created in step 2. This will assess the slider's behavior with its preset value in the composition.
  4. Create a Document Type:
    • Allow the document type to be created as a root node. This will simplify testing and ensure that the document type is accessible.
    • Add the composition created in step 3 to the document type. This is where the issue with preset values will be observed.
    • Re-create the same exact fields as in the composition, but place them on the document type itself 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 directly on the document type.
  5. Create the Document Type and Save: Create an instance of the document type and save it without touching any of the inputs/fields. The goal here is to observe the behavior of the preset values without any manual adjustments.

By following these steps meticulously, you will be able to reproduce the bug and verify the issue with preset values in compositions within Umbraco 16. This detailed guide ensures that you have a clear and repeatable process for identifying the problem, paving the way for effective solutions.

Expected Result

When working with Umbraco compositions, the expectation is that preset values defined within the composition's data types should be automatically applied when a new document type is created. This behavior streamlines content creation and ensures consistency across the website. In this section, we will delve into the specific expected results for the bug we are investigating. Understanding these expectations is crucial for accurately assessing the issue and determining the appropriate course of action. Let's explore the anticipated outcomes when preset values are correctly applied within Umbraco compositions.

The expected result is that both the composition fields and the direct fields should take their preset values automatically upon saving the document type. This behavior ensures that default settings are correctly applied, reducing manual configuration and maintaining consistency across content. Understanding this expected outcome is crucial for accurately identifying the bug and verifying the effectiveness of any solutions implemented.

Specifically:

  • Both the composition and the direct fields should take their preset values.

Actual Result

In contrast to the expected behavior, the actual results observed when reproducing the bug reveal a discrepancy in how preset values are handled within Umbraco compositions. This section will detail the actual outcomes of the reproduction steps, highlighting the inconsistencies and issues that arise. Understanding the actual results is crucial for pinpointing the root cause of the problem and developing targeted solutions. Let's delve into the specifics of what happens when preset values fail to apply correctly in Umbraco compositions.

The actual results differ significantly from the expected outcomes, highlighting a critical issue with preset values in Umbraco compositions. This section will provide a detailed account of the observed behavior, contrasting it with the anticipated results. Understanding these discrepancies is essential for diagnosing the bug and formulating effective solutions. Let's explore the actual results and their implications for Umbraco development and content management.

The actual results are as follows:

  1. Direct fields take preset values correctly. This confirms that the preset value functionality works as expected for fields directly added to the document type.
  2. Composition fields do not take preset values and are then null in their respective published content access (Delivery API, etc.). This is the core of the bug, indicating that preset values within compositions are not being correctly applied, leading to data inconsistencies and potential issues with content delivery. This discrepancy can significantly impact the functionality of your Umbraco site, as content relying on these preset values may not display or behave as expected.

    using Umbraco.Cms.Core.Events;
using Umbraco.Cms.Core.Models;
using Umbraco.Cms.Core.Notifications;
using Umbraco.Cms.Core.Services;
using Umbraco.Cms.Core;
using Microsoft.Extensions.Logging;

namespace YourProject.EventHandlers
{
    public class ContentSavingHandler : INotificationHandler<ContentSavingNotification>
    {
        private readonly ILogger<ContentSavingHandler> _logger;

        public ContentSavingHandler(ILogger<ContentSavingHandler> logger)
        {
            _logger = logger;
        }

        public void Handle(ContentSavingNotification notification)
        {
            foreach (var entity in notification.SavingEntities)
            {
                if (entity.ContentType.Alias == "yourDocumentTypeAlias") // Replace with your document type alias
                {
                    if (entity.IsNew)
                    {
                        try
                        {
                            // Set default values for composition fields
                            if (entity.GetValue<bool?>("yourToggleAlias") == null)
                            {
                                entity.SetValue("yourToggleAlias", true); // Replace with your toggle alias and default value
                            }

                            if (entity.GetValue<decimal?>("yourSliderAlias") == null)
                            {
                                entity.SetValue("yourSliderAlias", 0.5m); // Replace with your slider alias and default value
                            }
                        }
                        catch (Exception ex)
                        {
                            _logger.LogError(ex, "Error setting default values for composition fields.");
                        }
                    }
                }
            }
        }
    }
}
    • This code snippet demonstrates how to use the ContentSavingNotification to set default values for composition fields when a new document of a specific type is being created. Remember to register this handler in your composer.
