[news.eclipse.modeling.mdt.ocl] Problem with Link Constraint (OCL)

[Ivo Petkov <ivo.petkov@xxxxxxxxx>]

Hello,

I posted my problem in GMF section, but there are no answers, so I decided to post it here too ( http://www.eclipse.org/forums/index.php?t=msg&th=152579&start=0&S=0af8f2b4cf467d9a4c4284607c0496aa )
