[Seaside] How configure seaside to avoid notifications?

[Sebastián Perez Escribano]

Hi list, I'm using seaside 2.8 and VW 7.6. In my model I have this:
     ...
     self changeState.
     self doSomething.
     ...
I have some seaside components to view changes over my model (using 
comet) and refresh when it is necesary. For instace in #changeState the 
model change and the component which is viewing must call another. But 
never executes #doSomething because a Notificacion was raised on the 
call. So, how can I configure seaside to continue executing before the call?

Thanks!
