we're observing some behaviour we can't seem to explain. We had a
problem with
application deadlocking. It turned out that the lock was ERDPage
(a ProjectWonder
component) which locks an editing context in awake() and unlocks
it again in sleep().
That sounds odd to find this in Wonder. This is a known unsafe way
to lock editing contexts. IIRC, this was one of the reasons that
the ERXEC technology was created - safe locking with D2W. Is this
some old component that never got updated?
ERD2WPage is the root page component for all of Wonder's D2W
pages. :-/
I can't find the original message to this thread, but: I posted a bug
about this against D2W about 6 years ago and nothing has happened so
far. Rather than holding my breath, I added the ERXEC unlocker which
fixes this problem. The locking code is still in ERD2WPage because a)
people might have older code that doesn't use ERXEC and b) might not
be able or want to use auto-locking for whatever reason (I didn't in
most of my projects until now).
So if you use either the unlocker or the auto-locking code, you should
be fine.
And PLEASE: do not cross post! Wonder stuff belongs on the Wonder list
and vanilla WO to the WO list. All you do is make us read the same
messages multiple times, which comes from our time to make replies.
