BIRT Report of Contraints by Constrained Element

brice9

I am using the BIRT plugin inside Rational Software Modeler. Is there a way to create a dataSet which has all the constrainedElements as rows, but has/joins the relevant constraint information such as name and constraint details?

Example:
ConstrainedElement
Constraint1
Constraint2
ConstrainedElement2
Constraint1
Constraint3
Constraint4
...
I have tried this but without success in joining the URIs:
oclEvaluate(resolveURI($elementURI),"Constraint.allInstances()->select(c | c.oclAsType(Constraint).constrainedElement->exists(ce | ce = self))")

Any ideas are very much appreciated!
