3.1 RC3, Solaris 8, Motif, CDE While trying to Be Stupid, I was rapidly switching between perspectives. When I stopped, I was in the CVS Repository Exploring perspective, and the CVS Respositories view was an error view. The following exception appeared in the details. org.eclipse.jface.util.Assert$AssertionFailedException: null argument; at org.eclipse.jface.util.Assert.isNotNull(Assert.java:149) at

STEPS TO REPRODUCE: 1.) Set-up a workbench with three perspective open and all their buttons visible in the perspective switcher. One of the perspectives should be the CVS Repository Exploring perspective, and when the workbench is shutdown the CVS Repository Exploring perspective should NOT be active. 2.) Open the workbench and switch between the two other perspectives a few times. The goal is to get the user interface lagging behind the actual mouse input. 3.) Switch to the CVS Repository Exploring perspective and switch away. 4.) Switch a few more times between the other two. 5.) Switch to the CVS Repository Exploring perspective and wait until the user interface catches up.
The view can be opened by closing it and then opening it again.
Is this still a problem in 3.3? PW
Changes requested on bug 193523
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.
