Here's an interesting one.
it is a FOL, that director can't intercept (?) events, which are
generated from xtras.
it is the same with MUI callbacks for example.
any error fails gracefully (??) and must be handled by the "owner" of
the event, which is the xtra.
Hi Brennan, hi Alex,
thanx for the info. A workaround would be to let the callback create a
timeout object (see code below which does succesfully throw an error).
So, I wonder, maybe it would be a good habit to ALWAYS use
1ms-timout-objects for xtra callbacks? What do you think?
