i've installed the latest Idea build#7584.
I have imported some Eclipse projects in one Idea project like separated modules.
When i try "Find Usages" for some API method from one module it doesn't find any usage in another modules. The scope i selected is "Projject" so i expect that it should check all sources into the whole module and find usages (as old Idea 6.x works).
When i put a module dependency it started to work. But i think that this is undesired behavior ?
