Well, I sort-of figured out what was going on. My boolean property
was called "isAdmin". The getter was "public boolean isAdmin()
{ return isAdmin }", which seems to be the problem (in this case the
property-name didn't match up with the getter function name. The
boolean property should have just been 'admin' to go along with the
"isAdmin()" getter).
Is this a bug? I'm annotating the getter (as opposed to annotating
the property) -- must the getter function exactly match the property
for Enhancement to work?
Thanks!
