Hi team, Benoit Wiart has ported the UIDUtil optimization to RPCUIDUtil https://issues.apache.org/jira/browse/FLEX-33852
However, looking at the code, the two classes have the exact same behavior, except the additional getUID(item:Object):String in UIDUtils I don't know why there were two classes in the first place, but isn't it possible to remove now the redundant RPCUIDUtil class and only use UIDUtils ? Maurice
