Hello,
I have a rule which creates an object in the consequence part and updates this object each time teh rule is executed. So the object has to be created only the first time.
So I always need two rules, one init rule which creates the object if it doesn't exist yet and one if it already exists and it should only be updated:
rule "init rule"
when
"condition"
AND
not OutputObject()
then
OutputObject oo = new OutputObject();
insert(oo);
rule "update rule"
when
"condition"
AND
oo: OutputObject()
then
#do something with the object
update(oo);
But is it really neccessary to write an extra rule only to create the output-fact initially? Is it possible/good style to make this in one single rule?
Appreciate your help.
Regards
Thomas
