---------------------------------------

             Summary: Decision Table (XLS) should support fixed conditions, such as SeatDesignation(isNeighborOf($guest))
                 Key: DROOLS-470
                 URL: https://issues.jboss.org/browse/DROOLS-470
             Project: Drools
          Issue Type: Enhancement
      Security Level: Public (Everyone can see)
    Affects Versions: 6.1.0.Beta2
            Reporter: Geoffrey De Smet
            Assignee: Michael Anstis
             Fix For: 6.1.0.Final


This DT should work:

||CONDITION||CONDITION||ACTION|
|$guest : SeatDesignation()|$neighbor : SeatDesignation(isNeighborOf($guest))||
|guestName == "$param"|guestName == "$param"|doSomething();|


Failing workaround 1: This workaround (as specified by the docs), does NOT work well, because it adds the same condition (isNeighborOf($guest)) multiple times in the same rule:

||CONDITION||CONDITION||CONDITION||ACTION|
|$guest : SeatDesignation()|$neighbor : SeatDesignation()|||
|guestName == "$param"|isNeighborOf($guest), guestName == "$param"|isNeighborOf($guest), guestAge == "$param"|doSomething();|



Failing workaround 2: Adding an extra, hidden column with that condition does not work when new rows are added because condition columns with an empty cell are ignored.
