Florian,


I'm pretty sure that ZSI can only deal with simple types so (for now  
at least) you'll have to break your dictionary (whatever) into simple  
types something like this (from __EnterVenue() in  
AccessGrid.VenueClient.py, which immediately follows a comment about  
this "feature" of zsi):
    self.venueState = VenueState(uniqueId=state.uniqueId,  
name=state.name, description=state.description, uri
=state.uri, connections=state.connections, clients=state.clients,  
data=state.data, eventLocation=evtLocation, tex
tLocation=state.textLocation, dataLocation = state.dataLocation,  
applications=state.applications, services=state.
services)
