Description zcrar70 2006-05-17 18:32:16 UTC
Moving an object (not all objects, just this one) in a UML diagram causes 100%
CPU usage (an infinite loop?)

To reproduce: 
open up the attached project in netbeans 5.5 preview (build) with enterprise pack
open up the only diagram int he ValidatorUML project
try moving the "ValidationSet" object in the diagram to the right

Hope this helps

I also experience this issue with simple class diagram (on Linux).
While it makes the IDE nearly unusable I'm raising priority to P2, in fact it 
should be P1 while it is performance bug.
Comment 3 Michal Zlamal 2006-08-01 13:49:08 UTC
Since we got no response/reaction in 1.5 month I'm raising the priority to P1 
because it is performance issue and makes UML nearly unusable.
Comment 4 Trey Spiva 2006-09-26 16:36:59 UTC
I am finding that all of the nodes are a little sticky when you first click on
the node.  However, after it starts to move that it is responsive.

However, I am not finding a 100% CPU usage.  You stated that an infinite loop
was being caused, does it CPU usage ever go back to normal or do you have to
kill the NetBeans process?

I tried the same thing on my windows xp laptop with 1GB RAM but could not
reproduce this problem using either the entpack preview or beta version. I also
tried on Linux FC3 remotely through vnc and could not reproduce either.
I think the submitter should try this again using entpack beta to see if it's
still reproducible.
Comment 6 Michal Zlamal 2006-10-04 07:23:32 UTC
It seems like it is working correctly now.
Comment 7 Peter Lam 2006-10-16 19:20:45 UTC
no longer reproducible.
