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
