Fixed the UDP notification using stager_notifyServices. Note that this function shoudl be removed from the stager specific part to avoid compilation of the stager client when calling it(e.g. RH)

Modified subrequestToDo so that it can take a list of types and returns a SubRequest for which the associated request is of one of these types

First version of code generation for new Umbrello (1.3.1). Still a lot fo details to change but this work on my machine and allows to use the new Umbrello for UML edition :-)
