Hi Derik,
I think this change:
2012-08-18 17:08 eal
* [r64430] /trunk/ptolemy/actor/Manager.java,
/trunk/ptolemy/actor/lib/hoc/LifeCycleManager.java,
/trunk/ptolemy/kernel/undo/RedoChangeRequest.java,
/trunk/ptolemy/kernel/undo/UndoChangeRequest.java,
/trunk/ptolemy/kernel/util/Changeable.java,
/trunk/ptolemy/kernel/util/NamedObj.java,
/trunk/ptolemy/moml/MoMLParser.java: Fixed long standing deadlock
that occurs while editing models while they run
is what is causing the stack trace like [1] below.
I'll take a further look tomorrow.
This change is fairly important in that it solves a long standing issue,
so we need
to fix the bug as opposed to just reverting.

Hey Christopher,
I updated my local copy of kepler to use ptII r64449 but I'm still getting
errors like [1] below, wild dragging behavior, and remaining dots.
I haven't seen any rogue floating upper-left endpoints yet though.

Hi Derik,
It seems like it is Edward's change:

* [r64418] /trunk/diva/canvas/interactor/BasicGrabHandle.java:
Prevent null pointer exception that can happen while editing a
model while it is running by checking the Figure of Site for the
connector being dragged.
The change is:

Hey Christopher,
Dan and I are getting an error[1] when trying to drag a relation from a port
today in Kepler.
I'm also seeing a few other issues that seem to happen after the above. I got
an NPE[2] from a click, have strange actor-drag behavior (actor drags wildly /
shoots off in one direction), and sometimes dots are left over on canvas at the
point where I clicked on the port. Also when I'm dragging out a relation I also
notice in the upper left corner of canvas a blue 'port endpoint' square
(generally only noticeable in the overview section in the lower left).
See attached screenshot to see dots and blue square.
