Description Michael Giroux CLA 2010-07-19 11:23:44 EDT 
Build Identifier: eclipse.buildId=I20100608-0911

I'm implementing several new modules, and so far none have been committed to SVN. When I attempt to view local history for one of the files I get the following error:

eclipse.buildId=I20100608-0911

Reproducible: Always

Steps to Reproduce:
1. select a module in the package explorer
2. select team / show local history context menu
3. NPE occurs
Comment 1 Tomasz Zarna CLA 2010-07-21 05:56:50 EDT 
Are these modules new resources (not yet committed, marked with "?") in a SVN shared project?

Yes.

BTW, the NPE does not occur on every one of these resources.  There are a few that display a message box indicating there is no local history.
Comment 4 Tomasz Zarna CLA 2010-07-21 11:39:42 EDT 
When you switch to History view for one of the modules and press Shift+Alt+F1, what does Plug-in Spy you just opened say about active view class and contributing plug-in?

Is it possible that you will export the project, so I can reproduce the bug on my side? You don't have to include all the files, just make sure the one causing trouble is there.

Sorry, I had to commit the code to SVN, and now, the problem no longer exists.  If I see it again I will be sure to save the project for you.

Comment 8 Eclipse Genie CLA 2019-07-19 15:40:57 EDT 
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.

If you have further information on the current state of the bug, please add it. 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.
