[news.eclipse.modeling.mdt.ocl] Re: def expression?

[Joel Greenyer <jgreen@xxxxxx>]

So, the def-expression is no query and createQuery(String expression) does not work. Instead, I have to use 
OCLHelper.defineAttribute(String defExpression), right?
The problem is that I can't find any examples of using the OCL API in the right way to handle different cases of 
expressions (queries and def-expression) that I have in my transformation rules.
Could anyone please provide a snippet how to do that or point me to some example that demonstrates how to do it?

Thanks a lot

Joel
