Hi
I am using myEclipse 7.1.1. and am having intermittent problems with null errors being displayed. Looking through the logs, is would appear to relate to the history window.
I either get several being reported during startup or else it will suddenly start to report issues during use.
The error is as follows

!ENTRY org.eclipse.ui.workbench 4 2 2009-05-12 07:51:08.560
!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.ui.workbench".

They are not serious – just annoying!

I would like you to try something for me. Could you switch to a new workspace and then try working there for a while. Does the problem persist in the new workspace as well? Im asking you to try this because I want to make sure this is not a workspace related issue.

Also, can you go to MyEclipse > Installation Summary > Installation Details and paste the information here for me.

I will try and work in another workspace asap but I am up against a deadline so it might be a couple of days.

One interesting thing was today I got different errors, still related to history but this time SVN History. I only note this because yesterday several of the files were not added to SVN but now they are so maybe it is related to these? There were 2 errors on startup and two files that were not in SVN/now are in SVN

new error as follows:

I think I have tracked it down.
What does seem to happen is that if I create a file in the non SVN project,the history window and history is displayed. If I do this in the SVN project, the history is not displayed – if there is already history for another file, this remains in the window. If this file is left open when the eclipse is started, the error occurs.
Now if new files are closed when the project is open, and then opened during the session this error then occurs.
This only happens IF the file has not been commited to SVN. It affects new files and files added( but not committed) to SVN (ie no SVN history. It does not affect a file once a commit has taken place
(I am using subVersion but this has only happened recently)
