Would you be in the position to share the source code so we can reproduce the problem? Most likely to be a problem with core, but we don't know for sure until we are able to reproduce. The best way forward is to get our hands on the source code, as Stephan said. If that's not possible, see if you can isolate this issue in a smaller piece of code. Hey guys thanks for the quick comments, i will not be able to share the code, but ill will try to reproduce it in a separate project/example and share it, Thanks again. (In reply to ilan dardik from comment #3) > Hey guys thanks for the quick comments, i will not be able to share the > code, but ill will try to reproduce it in a separate project/example and > share it, > Thanks again. Any success so far? This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug. If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie. |
