[rules-users] Event wait constraint syntax

[Ajay.Gautam at rbs.com]

I am trying to figure out how to specify the constraint for Event wait.

The rules flow diagram attached would be launched for each incoming "request". The request is set in a process scope variable (reqIn). Each request has a *tag* associated with it.

The event wait in question is waiting for a response event with the same tag value.

How would I create a constraint rule to match this?
I guess the bigger question here is, how do I access the process scope request variable in the constraint?

Something like:


RFQResponse (tag == reqIn.tag)



PS: When I try this, I get an error: "Unable to create restriction '[QualifiedIndentifierRestr: == reqIn.tag ]' for field 'tag' in the rule 'RuleFlow-Milestone-com.rbs.gbm.pm.RFQ-WorkFlow-21' : [Rule name='RuleFlow-Milestone-com.rbs.gbm.pm.RFQ-WorkFlow-21']"


Any help / pointers would be highly appreciated.

Thanks

Ajay Gautam
