Hi,
I am trying to use eval block in one of the rules and am a bit confused
about it. The rule is something like this:
rule "LastCapacity"
when
e: Execution(lastCapacity:lastCapacity,parentOid:parentOid)
eo:
ExecutionOrder(entityOid:entityOid,msgType:msgType,execType:execType)
eval(lastCapacity != null && entityOid == parentOid && msgType ==
"8")
then
..................
end
where Execution and ExecutionOrder are 2 objects that are linked by an
ID. I expect eval to return true for certain sets of objects that I
send. But, the above rule exits without running the consequence. On the
other hand, when I write the rule as:
rule "LastCapacity"
when
e: Execution(lastCapacity:lastCapacity==null,parentOid:parentOid)
eo: ExecutionOrder(entityOid:entityOid == parentOid, msgType == "8")
then
.............................
end
the rule triggers the consequence for same set of objects. I thought
that if the expression in eval block comes out to be true, the
consequence will be triggered. Am I missing something obvious here?
Thanks
Malay Shah
