Hi,
i'm trying to finish a code that builds dynamically a Criteria object.
I got stuck at the in method of Restrictions.
Here is what i try to do:
return (SimpleExpression) findMethod(criteriaRestriction, restrictionOp, restrictionOpParamTypes).invoke(null, "id", new Object[] {1,2});

The method is found correctly, but when it is invoked, it fails with the following error:

java.lang.ClassCastException: org.hibernate.criterion.InExpression

That's the only info i got :(

Anyone?

Problem solved!
Sorry for this, i forgot that the in method does return a Criterion object, instead of SimpleExpression, which i was casting to.
The exception is because of the insuitable cast.
