Open type (Ctrl-Shift-T) does not find types

[Zhenya_Merom]

Hello all,
Eclipse does not find certain classes that exist in the workspaces when Open Type (Ctrl-Shift-T) used. "Problematic" classes are from one certain directory. At the same time these classes can be found by Open Resource (Ctrl-Shift-R) and are perfectly compiled.

What settings should be changed to fix the problem?

I have exactly the same problem as you. Does somebody know how this could be?
My type filters list is emtpy.
I do have several projects opened.

Sometimes, the indexes that Eclipse use for searching the types, get corrupted. You can clear the Open Type indexes by going to <Workspace>/.metadata/.plugins/org.eclipse.jdt.core and deleting all files there. The indexes will be re-built the next time you use open type.

Note that this is a empirical observation, and you may delete some JDT saved data that you don't want to delete. I observed no ill effects, but for safety you could try deleting just the *.index files and the "savedIndexNames.txt", and see if it works.
