Nice, now do the actual comparison inside the method so you can handle the nullpointer that will be sure to come eventually.

eval(workflowData.isValueEqual("KST", "$1"))

An eval needs to evaluate to true or false, such as

eval(myMapWrapper.get(“KEY”).equals(“SOME_VALUE”))

You may want to wrap your map in another class that you assert into the engines working memory.

Then you can access the contents of the map with an eval

eval(myMapWrapper.get(“KEY”).equals(“SOME_VALUE”))
