But how for example will it then be possible to run time intensive functions while updating the process status within the gui? I think in a MVC or event driven environment it must be possible to completly seperate the business logic from the gui. In Swing for example it is the usual way to put time intensive actions into an own thread. e.g. time consuming database queries of which the results shall be displayed after a while, without freezing the whole gui.
