[Pydev-users] [Users] Problem with 'non-PyDev Projects' filter

[SourceForge.net <no...@so...>]

The following forum message was posted by piotr_dobrogost at http://sourceforge.net/projects/pydev/forums/forum/293649/topic/4734668:

0. Make sure you have some PyDev projects (Python nature) and some CDT projects
(C/C++ nature).
1. Activate PyDev perspective
2. In PyDev Package Explorer choose 'Customize view...' and on 'Filters' tab
check 'PyDev: non-PyDev Projects' and click OK.

Result:
Some C/C++ projects disappear but other do not.

Any idea what could be wrong?
