Michael,
Well done, many thanks.
I've meantime gone back to jdk1.3 ! Now, dare I go back forward again to
jdk1.4 ? (Guess that's my problem to decide!)
I'm guessing your excellent work is so far a kind of temporary workaround?
Do you see this getting incorporated into a new excalibur jar in cocoon CVS
in the near future?
Would that be someting Berin would do?
If not, could you advise me which excalibur sources to edit (CVS - which
branch, or dist, or what)
and also which jars to build excalibur against, and where to get them?
I'm a bit new to the above (cocoon itself usually builds so nicely without
tweaking!)
and when I tried it, the resulting jars I built did not sit well with logkit
when I subsequently rebuilt cocoon :-{
Any ideas on this ?
Thanks again. Guess I'm not the only one who will benefit!
Christopher.
