Christoph,
There seems to be a compiler bug (the exception you received form polyglot). This compiler exception is the reason you see the weird behavior in X10DT. Basically, the compiler is behaving the same way when run with x10dt - it throws an exception and does not provide a valid AST structure for X10DT. As a result, X10DT has nothing to show, no error message and since it doesn't have a valid AST, the editor services are unavailable too. It would be great if you could file a JIRA against the compiler for the compiler exception - we are actively working on fixing compiler exceptions.
