  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"))

    i got a java class with a hashmap containing string keys and values.

     

    i want to access the values from a condition on a decision table. 

     

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

     

    how can i do this?

     

    i tried but got an 

    unknown:7:50 Unexpected token

    error.

    greetings sascha
