             Summary: DMN Validation does not provide a proper descriptive error message
                 Key: DROOLS-5017
                 URL: https://issues.redhat.com/browse/DROOLS-5017
             Project: Drools
          Issue Type: Bug
          Components: DMN Editor
    Affects Versions: 7.32.0.Final
            Reporter: Duncan Doyle
            Assignee: Michael Anstis
         Attachments: Screenshot 2020-02-06 at 11.25.18.png, vacation-days.dmn

The attached DMN file is invalid as it contains a trailing space in one of its decision nodes (Base Vacation Days). I've checked with [~tari_manga], and according to him, the backend DMN validator is capable of detecting the problem and giving a proper error message. However the DMN editor in the workbench does not give any user friendly hint what the problem is, and hence it's almost impossible for a user to figure out what's wrong.

I've attached both the DMN model and  a screenshot of the error message displayed by our editor.
