During List Edit / Inside Embedded Lists, changing the value of a dropdown always sets its dependent to -- None -- even if the same value is present Description During List Edit / Inside Embedded Lists changing the value of a dropdown always sets its dependent to -- None -- even if the same value is present.

Steps to Reproduce

For embedded lists: 1. Create a custom table called u_test_table. 2. Create two string fields: u_category and u_subcategory. 3. Add two choices for u_category: Category1 and Category2 4. Set category1 as the default value of u_Category. 5. Add thee choices for u_subcategory: - value = 100 , dependent value = category1 - value = 100 , dependent value = category2 - value = 200 , dependent value = category2 Set the default value of u_subcategory to 100. 6. Create a reference field called u_incident and refer to the incident table. 7. Go to the incident form, right-click in the form header, and choose Configure > Form Layout. 8. Add "u_test_table" as an embedded list on the form. 9. Open the incident.do form and double-click on the category. Note that "category1" and "100" is selected. 9. Change the first dropdown to "Category2". Instead of the value in Subcategory dropdown remaining "100", the value becomes " -- None --".

For List View (v2)]: 1. Create a custom table called u_test_table. 2. Create two string fields: u_category and u_subcategory. 3. Add two choices for u_category: Category1 and Category2. 4. Set category1 as the default value of u_Category. 5. Add three choices for u_subcategory: - value = 100 , dependent value = category1 - value = 100 , dependent value = category2 - value = 200 , dependent value = category2 Set the default value of u_subcategory to 100. 6. Open u_test_table.do and create a new record with category set to "category1" and subcategory set to "100". 7. Go to u_test_table_list.do and double-click on the Category field then change the dropdown to "category2". Instead of the value in Subcategory dropdown remaining "100", the value becomes " -- None --".

Note: If the same record is opened on a form this works as expected.
