---------------------------------
Fix Version/s: 3.1-m2
Resolution: Out of Date
I just tested in trunk and it is not raising exceptions anymore. The only problem I found
is that as no-loop only prevents the same rule from activating, the attached rule-set is
in loop because of rules 2 and 4. A simple fix, just for the sake of the test is to
rewrite rule 2 as:
rule "Rule-2"
no-loop true
when
$m : Machine( entryAlreadyCreated == false )
then
System.out.println("DEBUG [Rule-2]---> Add Machine to MachineEntry");
MachineEntry me = new MachineEntry();
me.setMachine($m);
assert(me);
$m.setEntryAlreadyCreated( true );
modify( $m );
end
Thank you for reporting and providing test cases. Let us know if you are still having
problems.

Mark Proctor commented on JBRULES-749:
--------------------------------------
yes I fixed this. during a modify it would retract ALL tuples nd none of them could get
back onto the agenda again, due to no-loop. when in reality it should only block the
current one, not all of them.
