-------------------------------------

Tom,

After looking over the jbpm source code I see that you have a FunctionMapper interface which is passed to your expression evaluator (ExpressionEvaluatorImpl).  What we need to be able to do is pass in our own FunctionMapper which is capable of mapping the Seam security functions.  It should be an easy matter for us to wrap the function mapper we already have with your FunctionMapper interface.  What isn't clear to me is how we tell jbpm to use the new function mapper.  I'll keep researching this but if you could point me in the right direction it would be great.

> Currently, jBPM uses its own forked EL (which is a problem to begin with....). This means that it can't see the s: functions.
> We need to fix this problem ASAP.
