Manfred Karrer a10ce23145 Add fallback to support old not updated clients ... If a updated client makes a param change request old client do not recognize that enum. To avoid exceptions ro null pointers we fall back to the UNDEFINED enum entry if available. As param value we show an empty string. Beside that issue no problems have been found so far with adding a new param entry.		2019-01-30 00:05:07 +01:00
