   @jomarko May be I was not clear earlier. Like you mentioned, a user tried to use editor, that contained this constraint definition [1]: which is invalid.
   [1]
   `not(null) and (string length()>0)`
   During this time an error message [2] is displayed in both Classic and New dmn editor.
   [2]
   `ERROR_EVAL_NODE: Error while evaluating node 'Hello New User' for dependency 'user': the dependency value 'Amy' is not allowed by the declared type (DMNType{ https://kie.apache.org/dmn/_B08C396C-3893-4572-91AE-335F99187350 : user })`

   Once user fix the constraint definition to be [3]:
   [3]
   `string length(?)>0`
   Then there are no warning/error messages and user is be able to evaluate the dmn model in new dmn editor similar to the old one.
