Threadsafety of JSF DataModel / TreeModel

[ma...@daimlerchrysler.com]

Hi,

well I was thinking about to improve the TreeModel for the tree2 but came 
to a more general problem regarding threadsafety.
When a component uses a local Model there are no problems at all, 
everything runs in one thread per request. Now if you move your model to 
any higher scope than request as far as I can see there are potentially 
problems with threadsafety ... in a multi-threaded servlet environment. 
Two views with different components using the same model could interfere 
each other. Ok, the user could provide a special model but with the 
concept of setting a row and than retrieving data about that row its 
somehow impossible to do a synchronization in the model that every 
component gets the right data for its row currently processing.

Is this a flaw in the spec or do I miss something here?
