If anyone is interested I can post this modified Cayenne 1.2 Modeler build on a web server.
Yes, please, post it. There are just too many projects using Cayenne 1.2, and since 3.0 is not "build-able" in a distribution (maven is not producing the same result as ANT yet), most projects will stay with it.
Thanks in advance, Ahmed. P.S. Maybe we could transform this ticket into' a "bug" request :), to be able to apply the patch on 1.2/2.0 :).
