/**
@short handle interactions non visible
@descr Sometimes it's necessary to use a non visible interaction handler.
He can't do anything, which a visible one can handle.
But it can be used to intercept problems e.g. during loading of documents.
In current implementation we solve conflicts for following situations only:
- AmbigousFilterRequest
- InteractiveIOException
- InteractiveAugmentedIOException
All other requests will be aborted.
