Fixed.
Jeez ... That took a good 45 minutes of frantically clicking to get
this to happen in the debugger. Fortunately once it happens once, it
continues to happen. I actually think it's related somehow to
specific files and it seems somehow related to collapsing code areas,
but I'm not entirely sure how. I didn't need to nail down the exact
triggering events, though, because the root cause of the NPE became
pretty obvious once I got it breakpointed.
It turns that one section of code was expecting an editor to be of a
certain interface, and the TemplateEditor (the HTML part of the
ComponentEditor) didn't implement the particular interface, which
caused it to return a null, which triggered an NPE later down inside
of Eclipse code (confusingly, all our code was out of the stack by the
time the NPE itself occurred). TemplateEditor now provides proxies for
about six additional common Eclipse editor interfaces just-in-case,
and I was able to get the previously-would-have-NPE'd error to happen
again with this fix in and it seems to work correctly now.
