Description saadia dhouib CLA 2010-08-17 09:22:12 EDT 
When moving inside a package a set of classes linked together through associations and generalizations, I have the following error:

!ENTRY org.eclipse.core.commands 4 2 2010-08-17 15:06:10.218
!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.core.commands".

impacted classes
Comment 2 Patrick Tessier CLA 2010-08-17 11:20:32 EDT 
the list contained null value, a test has been added.

Can you test before close the bug.
Comment 3 saadia dhouib CLA 2010-08-18 03:12:23 EDT 
I have made a test, there is no more errors. But I can not see all the classes inside the package. Even if I enlarge the package, I can't see correctly all the classes and associations.
Comment 4 saadia dhouib CLA 2010-08-18 03:16:28 EDT 
I works fine now, I have used the "arrange all" button, and I can see all the classes inside the package.
Comment 5 Patrick Tessier CLA 2011-02-28 08:13:53 EST 
I close the bug
