[News.eclipse.technology.gmf] OCL constraints disabled and no preference

[alan newton <alan.newton@xxxxxxxxxxxxxx>]

Hi

I don't know if anyone can help, but I am having trouble adding OCL 
rules to my GMF application.

I followed the instructions within GMF Tutorial 2, including setting 
"Validation Enabled" and "Validation Decorators" to True, Modifying the 
"Validation Provider Priority" to Medium.  However, when I run the 
application in the Problem view I get Messages "IRJA00301 The Constraint 
..... is disabled. It will not be evaluated." and there is no 
"Validation Constraints" preference window.

Does anyone know what I have neglected to do.

Thanks

Alan
