I have the following issue with Modern UI:
In one package I create a column.
In another package I add a field / logic that depends on that column.
Everything works fine when I develop Modern UI in Visual Studio — after build, all changes are visible on the screen and work correctly.
But when I add Modern UI files into packages and publish them in another instance of Acumatica ERP, I get errors (field/column not found).
I understand that this approach is not recommended, but I still need to make it work.
Is there any way to handle this scenario?
