ClassCastException on .splitNode().constraint()

created by Connie Yang in jBPM - View the full discussion

Hi,

I'm using jbpm-flow-5.2.0-SNAPSHOT.jar and got a ClassCastException below with the following Drools flow snippet. I've tried mvel dialet as well and got the same error.

.splitNode(1010).type(Split.TYPE_XOR).name("splitOnShouldActivate")

.constraint(305, "should activate", "code", "Java",

"(Boolean)(context.getVariable(\"shouldActivate\")) == Boolean.TRUE")

.constraint(2000, "should not activate", "code", "Java",

"(Boolean)(context.getVariable(\"shouldActivate\")) == Boolean.FALSE")

.done

Exception in thread "main" java.lang.ClassCastException: org.jbpm.workflow.core.impl.ConstraintImpl incompatible with org.jbpm.process.instance.impl.ConstraintEvaluator
