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,

Alan
