Created attachment 139404 [details] Screenshot Summary: Cannot create Master/Detail form within Default package 1. Add new Swing GUI form > Master/Detail Sample form. Keep the package as Blank (Default package, this will show a warning) 2. Press Next 3. The form is Disabled and displaying an error stating Creating of Master/Detail form from default package is not allowed. Logical solution: This show Either allow to create master/detail from from the 2nd Wizard screen or From the 1st screen it should not allow to navigate to the 2nd screen
Adjusting bug priority, I think it is only a minor inconvenience that you are not blocked in using default package already in the first step, but on second. The warning in the first step comes from a general component for entering a location of a java file, we will need to learn it some parameter to specify whether default package is just a warning or error.
