> The decision node does not evaluate scripts in conditional transitions.
> Indeed, the execute method of node type decision does not check what type of condition it is.
> Listing of the wrong code :
> (file Decision.java lines 120-135 in Jbpm Jpdl 3.2.2)
>       } else {
>         // new mode based on conditions in the transition itself 
>         Iterator iter = leavingTransitions.iterator();
>         while (iter.hasNext() && (transition==null)) {
>           Transition candidate = (Transition) iter.next();
>           
>           String conditionExpression = candidate.getCondition();
