             Summary: XLS Decision tables: Add support for Condition column DRL fragments
                 Key: JBRULES-3448
                 URL: https://issues.jboss.org/browse/JBRULES-3448
             Project: Drools
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
            Reporter: Michael Anstis
            Assignee: Michael Anstis
             Fix For: 5.5.0.Beta1


Condition columns in XLS Decision Tables have a row for Object type and a row for code "snippet". The code snippet is taken as predicates within the Object type; for example:-

{code}
CONDITION    | CONDITION
----------------------------
           MyFact
----------------------------
field1 ==    | field2 ==
----------------------------
a            | b
{code}

This is rather limiting (and certainly not conducive to decision table round-tripping). Ideally we need to support:-

{code}
CONDITION
----------------------------------------------
MyFact( field1 == $param1, field2 == $param2 )
----------------------------------------------

----------------------------------------------
a,b
{code}

Even more ideally it'd be good to be able to register "column handlers" so this can be extended easily.
