Hi, all.
I'm feeding an XML message into a drools service-unit, which acts as a
routing engine.
If a piece of the XML message is missing, I have a rule (number 1) that will
route the message to a service that will fill it in. The message should
then be re-evaluated by the rules. Since the missing piece is filled in,
other rules will fire (including number 2 as shown). I expect that I should
be able to do this through the following on a "then" clause:
rule "Rule number 2"
when
me : Exchange( status == Exchange.ACTIVE, in : in != null )
eval( in.xpath("//*[local-name() = 'TheMissingPart']") )
then
jbi.route("service:urn:CompletionService");
end
rule "Rule number 1"
when
me : Exchange( status == Exchange.ACTIVE, in : in != null )
eval(!( in.xpath("//*[local-name() = 'TheMissingPart']") ))
then
jbi.route("service:urn:MissingPartService");
modify(me);
end
The missing part is being filled in by the MissingPartService, but the rules
are never re-executed on the new message exchange, which I figured should
happen using the "modify(me)" call.
Can anyone shed light on this issue?
Thanks.
Justin
