Updated Dev. platform using WO523Developer.dmg, now I get the error on the
Dev platform as well as Deploy - I guess this is a 'good' thing.  Here is
the stack trace.  I cut-n-pasted it from the browser window (it's not
pretty).  Again, the error occurs when sending the context the
.saveChanges() command.  Is this legible?  (thanks!)
