Thanks for the replies. Managed to get it working. btw. By "do not work" I meant the root of the tree is rendered but the children are not. No exceptions were thrown. The solution is to put the trinidad api reference in application.xml <module> | <java>trinidad-api-incubator-m1-SNAPSHOT.jar</java> | </module> and put trinidad-impl-incubator-m1-SNAPSHOT.jar file in web-inf/lib Back to one kind of stuff, excellent.
