[jboss-jira] [JBoss JIRA] (DROOLS-4469) Invalid result with collect, mvel and ForceEagerActivationOption.YES
Martin Weiler created DROOLS-4469:
-------------------------------------
Summary: Invalid result with collect, mvel and
ForceEagerActivationOption.YES
Key: DROOLS-4469
URL: https://issues.jboss.org/browse/DROOLS-4469
Project: Drools
Issue Type: Bug
Components: core engine
Affects Versions: 7.25.0.Final
Reporter: Martin Weiler
Assignee: Mario Fusco
A rule updates a list in a fact:
{noformat}
rule "Init"
dialect "mvel"
when
$fl: FactWithList(items.size()==0)
then
$fl.getItems().add("A");
$fl.getItems().add("B");
update($fl);
end
{noformat}
A second rule verifies if other facts exist, matching the items in the updated list:
{noformat}
rule "Expected Outcome"
dialect "mvel"
when
$fl: FactWithList($itemList : items != null)
$l: java.util.ArrayList(size > 0) from collect(FactWithString($itemList
contains stringValue));
then
System.out.println("--> Rule: " + kcontext.getRule().getName() +
" fired, " + $fl + ", collect list: " + $l.size());
end
{noformat}
This rule is *not* fired if
* mvel dialect is used *and*
* Drools is executed with {{ForceEagerActivationOption.YES}} (jBPM use case)
Note: This worked in 7.17 and earlier!
