----------------------------------------

Well.. the error messages suggests KIE's DMN validation barfed when trying to validate the model...

I will however investigate and report back soon.

> 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.
