Hi,
Thanks for the response.
That doesn't seem to be right - this is what is produced from the Compiler.
// rule values at A9, header at A3
rule "Test rule_9"
when
$c : ConditionObject(somefield)
$a : ActionObject(this != null == "X")
EmbeddedObject(myField == AnEnum.SomeOtherValue) from
$c.embedded
then
ActionObject.someMethod2(50);
$a.someMethod("someOtherValue")
$a.someMethod3(B)
end
Is there a way to have a "when" rule produced where the data table row, for
that CONDITION is empty ?
The hack version I can work out is
> CONDITION
