Thank you Dave for the reply. I would try the approach you suggested

Subject: Re: [X10-users] X10 Compiler query
Hi,
Sorry to be slow answering.
My advice would be to invoke the compiler in a debugger (if you use eclipse to
develop, then there should be an x10c/x10c++ launch configuration defined for
you), set breakpoints, step through the execution and try to see where control
is going.
Most likely there is some small detail that is causing the goal to not be
scheduled or the vistor to not be invoked in the way you expect.
Sorry to be not very specific, but the general approach should help you find
out what is going on.
