I'm not sure if end() will help (not in every case) as you could have
to cast to ChoiceType whatever is returned by end().
My solution to those problems was something like:
from(cnn).
choice().
when(xpath(filter)).to(direct:subflow).otherwise().to(direct:something-else);
from(direct:subflow).multicast().to(im, archive);
This way you cannot hit any 'class type' problem in your DSL.
Sometimes it could be important to add in your subflow something like
errorhandler(noErrorHandler()) so it will not have its own error
handler.
