[rules-users] [droolsflow] Code-based constraints for EventWait nodes - is this possible?

[Alan.Gairey at tessella.com]

Can the constraint for an EventWait node in a flow be code-based (rather 
than rule-based)? The Eclipse plug-in (v 5.0.1) doesn't allow this to be 
specified, unlike say for a Split node, although the relevant XML can of 
course be edited.
Trying to load such a process flow results in a NullPointerException, 
because the constraint is always interpreted as a rule.

Ideally what I'd like to do is have an EventWait node where the constraint 
tests the value of a process variable. This then leads me to another 
question; is there a way of setting the value of a process variable via 
the Drools Flow API?

Thanks in advance for any help,
