[news.eclipse.modeling.mdt.uml2.ocl] Re: How to change the error message

["Christian W. Damus" <cdamus@xxxxxxxxxx>]

Hi, Andreas,

No, those messages aren't very useful.  I can imagine a number of ways of
customizing the error message, including but not limited to:

  - adding another detail to the constraint annotation in the Ecore model
  - looking up a string in a properties file, keyed by the constraint ID
    (would support localization)

The codegen example in my article is just that:  an example.  Specifying
error messages wasn't its purpose (only specifying constraints).  Of
course, you are free to extend the example to address any concerns that it
doesn't  :-)

Cheers,

Christian
