Hey Christopher,
<div>Dan and I are getting an error[1] when trying to drag a
relation from a port today in Kepler.</div>
<div>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). </div>
<div>See attached screenshot to see dots and blue square.</div>
