<br><font size=2 face="sans-serif">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.</font>
<br><font size=2 face="sans-serif">Trying to load such a process flow results
in a NullPointerException, because the constraint is always interpreted
as a rule.<br>
</font>
<br><font size=2 face="sans-serif">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?</font>
<br>
<br><font size=2 face="sans-serif">Thanks in advance for any help,</font>
