Using an instance of 25.200.0020 (clean install), I need to customise screen AP303000 to add some fields (specifically AddressLine3), but on opening the Modern UI Editor from the Customization Project Editor for that screen, I get the error message:
In HTML extension “C:\..\FrontendSources\screen\src\screens\AP303000\extensions\AP303000_PersonalDataPrivacy.html” for screen ‘AP303000’ child node ‘QP-FIELDSET’ has AFTER attribute with ‘#groupAccountAddress’ but screen HTML doesn’t contain any elements that satisfies such querySelector.
I can work around this locally by renaming the source files AP303000_PersonalDataPrivacy.html and .ts (adding a suffix of .x). But I’m concerned that the same hack won’t be possible in production.
