[rules-users] ClassCastException on .splitNode().constraint()

[cyang]

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

*
