Hello,

I'm unsure if this is the correct newsgroup for questions related to the
Check language - please feel free to crosspost if it isn't...

I'm thinking about replacing some rather clumsy hand-written Java
validators with Check expressions using the extension point
org.eclipse.xtend.typesystem.emf.checks. I need to execute my checks
instead of the default EMF checks because the error messages generated
by the default checks are unsuitable for the users. From the
documentation I understand that I have to set override to true, and it
seems to work.

At the same time, I want to keep things organized by splitting my checks
into several .chk files. I can add multiple checkFile elements inside a
metaModel element, but I'm getting strange results. If I read the
implementation of CheckRegistry correctly, the validators that
correspond to each of the files replace each other as soon as override
is set to true. This looks like a bug to me - is it one?

Thanks
Volker

Hi Volker,

the m2t newsgroup is a better match for questions related to the Check
language.

I hope that somebody will jump in and answer your actual questions.

Regards,
Sebastian
