    Problem with RuleFlowNodeContainerFactory.splitNode(...) method

    Santhosh Bhat Newbie

      Within the source of class org.jbpm.ruleflow.core.factory.SplitFactory, inside the method

       

      constraint(long toNodeId, String name, String type, String dialect,

      String constraint, int priority)


      the author is creating an instance of class

      org.jbpm.workflow.core.impl.ConstraintImpl. But inside the

      org.jbpm.workflow.instance.node.SplitInstance.executeStrategy(...)

      method, another author us casting


      ConstraintEvaluator constraint = (ConstraintEvaluator)

      split.getConstraint( connection );


      This is resulting in a ClassCastException, here's the stack trace.

       

      Caused by: java.lang.ClassCastException:

      org.jbpm.workflow.core.impl.ConstraintImpl cannot be cast to

      org.jbpm.process.instance.impl.ConstraintEvaluator

      at org.jbpm.workflow.instance.node.SplitInstance.executeStrategy(SplitInstance.java:83)

      at org.jbpm.workflow.instance.node.SplitInstance.internalTrigger(SplitInstance.java:63)

      ... 50 more

       

      you might think Why I am using SplitFactory?

      I am writing a code which will dynamically generate the workflow

      process using the worflow process API (RuleFlowNodeContainerFactory)

       

      Can anyone please tell me how I can resolve this error? This error seems

      to be internal to JBPM..
