I am currently using Activiti 5.13 version and trying to create my own expression evaluator which accepts a string expression and DelegateExecution as show below.<sequenceFlow id="flow1" sourceRef="theStart" targetRef="theTask"> <conditionExpression xsi:type="tFormalExpression"> <

Hi,

to get sequence flow which is evaluated you should change


    while (outgoingSeqFlow == null && transitionIterator.hasNext()) {
      PvmTransition seqFlow = transitionIterator.next();
      
      Condition condition = (Condition) seqFlow.getProperty(BpmnParse.PROPERTYNAME_CONDITION);
      if ( (condition == null && (defaultSequenceFlow == null || !defaultSequenceFlow.equals(seqFlow.getId())) ) 
              || (condition != null && condition.evaluate(execution)) ) {
        if (log.isDebugEnabled()) {
          log.debug("Sequence flow '{}'selected as outgoing sequence flow.", seqFlow.getId());
        }
        outgoingSeqFlow = seqFlow;
      }
    }

Condition is evaluated only from execution, which does not contain information about flow to take.

Martin
