I'm getting weird results with this patch. When I first applied it, it
displayed the dependents and dependencies on the test exclusion
constraint, but without an icon on the entry on the Depends panel. I
see no entries for a primary key constraint though, and after
selecting one, if I reselect the exclusion constraint, I then no
longer see the dependencies/dependents listed. If I try to refresh the
node, I get the following exception:
