I have a problem with an Idea 11.x project where control-n doesn't show all matching classes. I've been using Idea for 10 years and generally know what I'm doing but am pretty stumped on this one.
I created a project from existing src. I've done it two ways. By default, Idea wants to create separate modules for the src and test trees. Control-n doesn't find any of the src code, only test. If I recreate the project with a single module containing src and test, marked appropriately under the modules/sources tab, I still get the same behavior where the src classes are not found, only test classes. If I open a src class by clicking it in the project browser, I get errors about classes and imports not being found, even though they're right where they should be.
Currently I'm having this problem with an internal codebase, but I think I once had it with Axis 1.x, fwiw.
