Description Sergey Petrov 2006-11-02 15:05:41 UTC

reproducible with coke, coco 061101_7
unable to reproduce in jse8

Hang or unstable work after addition of combined fragment within another one or
within shown interaction boundary.

steps to reproduce:
1. create package with scoped sequence diagram
2. add two lifelines
3. invoke 'Show Interaction Boundary' from diagram context menu
4. place combined fragment within the boundary
ide hangs (sometimes may response to some actions and hangs again)
java cpu useage goes to 90-99% for a long time (entire system became slow)

in steps with two combined fragments I was able to invoke context menu twice
after step 4 and to drop one more lifeline, and all hangs completely

StackOverflowError in IDE log file

Comment 4 Kris Richards 2006-11-21 21:34:11 UTC

removed super.doDraw for the InteractionFragmentDrawEngine.doDraw method. This takes care of the 
first noted StackOverflow.

Comment 5 Kris Richards 2006-11-21 21:37:22 UTC

both issues fixed.

Comment 6 Sergey Petrov 2006-11-22 11:35:50 UTC

which two issues?
initially:
-about combined fragment within interaction boundary - fixed
-combined fragment within combined fragment - still reproducible

Comment 7 Sergey Petrov 2006-11-22 11:37:25 UTC

(tried with 061121_17)

Comment 8 Sergey Petrov 2006-11-22 12:16:15 UTC

even with boundary+fragment there is issue: StackOverflow on fragment resize (I
can file as separate issue)

Comment 9 Kris Richards 2006-11-22 17:42:34 UTC

removed super.doDraw for the CombinedFragmentDrawEngine.doDraw method.

Comment 10 Kris Richards 2006-11-22 17:58:47 UTC

can you please file a separate bug concerning the fragment resize; including a "how to reproduce".

Comment 11 Sergey Petrov 2006-11-23 13:40:46 UTC

can't reproduce resize issue with 061123_1
