Hi Andrew,

the problem is that when you pass a *string* to rpc, this is currently
not parsed in the same module context in which the goal gets called.
This could be considered a bug, so we'll fix it.

For the time being, use either a string in canonical syntax, i.e.

	eclipse.rpc("&::(A, [a,b])");

or use the Java-Eclipse type mapping, i.e. pass a CompoundTerm:

	Collection abList = new LinkedList();
	abList.add(new Atom("a"));
	abList.add(new Atom("b"));
	eclipse.rpc(new CompoundTermImpl("&::", null, abList);


Best regards,
Joachim
