When using syntactic predicates I sometimes get an error: "The rule call is part of a call hierarchy that leads to a predicated unordered group". What does that mean and how can I resolve the problem? I have not found any information about it over the internet. (I told about this error here: http://www.eclipse.org/forums/index.php/mv/msg/358314/881052/#msg_881052)

Oleg,

I've the strong impression that you use way too many syntactic
predicates :)

It is not possible to use a predicate that works on an unordered group.
That's because we had to tweak Antlr a lot to get Unordered groups right
and it's simply not possible to get that working together with manually
defined predicates with reasonable effort.

Regards,
Sebastian
