#26520

Form creation with "foreign objects" and individual template fails

AppEditors

When a form is created using the Form Editor and the "External Objects" option is selected, you can configure another form to display the external objects.

If this happens, a NullPointerException occurs:

Caused by: java.lang.NullPointerException

Cause

Since there are no objects in design mode, `tl:FormField`s are created for `tl:AttributeUpdate` in "create" mode. Since no identifiers exist for the objects of the base type and the "foreign type" that are supposed to be created, the system attempts to use the same transient object, which fails.

Solution

Use a "domain" when creating the AttributeUpdate.

Test

Open the form editor for a type X` != `User Account.
Select "Objects".
- Here, select the User Account type.
- Configure the form.
- Select the "Username" attribute here.
Add an attribute of type X.
- Expected result: No NullPointerException occurs.
