Error evaluating XOR condition in ruleflow (in 5.2.0 worked in 5.0.1)
---------------------------------------------------------------------
Key: JBRULES-3183
URL: https://issues.jboss.org/browse/JBRULES-3183
Project: Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: drools-core (expert)
Affects Versions: 5.2.0.Final
Environment: Windows XP, Java 6, Eclipse 3.7.0, Drools plugin from JBoss Tools
3.2
Reporter: Lubos Pechac
Assignee: Mark Proctor
XOR split below produces error for condition:
not GBN2GFact()
or
GBN2GFact( payComps == null || payComps.size == 0 )
payComps is declared in POJO GBN2GFact:
List<PayrollComponent> payComps = new ArrayList<PayrollComponent>();
Error is:
