             Summary: [DMN Designer] Editor allows node with prefix/trailing space
                 Key: DROOLS-5060
                 URL: https://issues.redhat.com/browse/DROOLS-5060
             Project: Drools
          Issue Type: Bug
          Components: DMN Editor
            Reporter: Matteo Mortari
            Assignee: Michael Anstis


I understand [DROOLS-5017] has been re-purposed to allow Info and Warn level messages be displayed on Stunner Validation dialog. That is fine.

But, imho, an UX point is not being considered, where is necessary instead.

By the DMN spec, a node should not have a prefix/trailing space, as space insensitivity would mandate 1 trailing or 2 trailing spaces are simply ignored etc.
The engine is lenient to avoid this crashing the evaluation, but still is a bad designed model to persist the node name (DRGElement name and its corresponding variable name) with those extra spaces IMHO.

Further, I consider is just the Analyst which slipped a space.

In my perspective, the editor should just strip away the prefix/trailing space:
* while Importing a DMN model from file Upload
* while editing a DRGElement and hitting OK to save its name

For your consideration, thanks.
