Hi Mike, I've never tried that before (a rule without the when part..) is
good to know that it works :)
Humm that's sounds weird.. why the dialect is affecting your Client
creation.
It could be that there is something wrong with the expression evaluation.
It looks like MVEL cannot compile the new Client(); expression -> at
java.lang.String.<init>(Unknown Source)
Did you try with something like:
then \n
Client c = new Client();
I'm just guessing here, because it looks strange

Hi Mauricio,
Thank you for the speedy reply. Ia m making rest call to web services
using jersey. I simplified the rule to the max. The 'when' is not really
needed. I get the exception on the call to "new Client()". Please keep in
mind it works without dialect "mvel".
Thank you very much
Mike
