Hi Steve,
From quick glance at the referenced document it is not clear how
exactly thread inheritance is done in ZK, still acting on my TODO
seems like a good idea in general. I'd appreciate a Jira on that. We
can add it to 3.0.
Thanks

Hi,
I've been playing with the ZK (www.zkoss.org) framework for
building AJAX
apps, and so far have found it rather impressive and easy to use.
Having hit my first roadblock now is getting DataContext, as each
ZK request
runs in a separate thread (see:
http://www.zkoss.org/smalltalks/zkacegi/zkacegi.dsp
) I think this is the problem why I can't get DC
with WebApplicationContextFilter and
DataContext.getThreadDataContext (). I
get "IllegalStateException: Current thread has no bound DataContext."
Looking into src for DataContext I see this comment // TODO: Andrus,
11/7/2005 - should we use InheritableThreadLocal instead?
So I subclassed DataContext and overrode the :
ThreadLocal threadDataContext
to be
InheritableThreadLocal threadDataContext
changed WebApplicationContextFilter to call my subclassed
DataContext and
bingo it works.
Not sure if anyone else has run into this kind of thing before? I
would
raise a JIRA issue but I'm not yet confident that this is the 100%
correct
solution.
