Description

SelectWrapper and FlatSelectWrapper should extends AbstractRichFucntion and process properly if the underlying functions extend RichFunction.

Things to be very careful about:

• backwards compatibility (we previously serialized conditions) - changes to those interfaces have to be done carefully
• we want to be able to add dynamic patterns in the future, so at some point we have to open also on control message arrival
