Couldn't open a composite actor at the second time
The kepler is in sensor-view suite.
1. Open a composite actor, do some changes.
2. Close the composite actor.
3. Save the workflow (don't close it).
4. Reopen the composite actor by click "Open Actor". It shows a very small windows only having a title.
I have to quit the kepler and reopen the workflow and composite actor. It is very annoying.
