[rules-users] accessing hashmap from condition on decision table

[Knapp, Barry]

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"))

decision table. 

		 

		e.g. map.get("mykey") 

		 

		how can i do this?

		 

		i tried but got an 

		unknown:7:50 Unexpected token

		error.
