Re: [Wicket-user] How to attach thread
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. regards /thomas Johan Compagner wrote: First of all you shouldn't really access the session in another thread.

Re: [Wicket-user] How to attach thread
You can still do that, but you need to reverse the logic: query the running thread for the required progress/data instead of pushing it from the thread to the session. The difference between Swing apps and web apps is that you can run the web app on multiple machines, where the session is shared between different servers. Another thing is that the session is managed by the web container, and can be serialized to disk or a database. Keeping (unmanaged) references to managed objects is not a wise thing to do. Don't call us, we call you is a good principle in this case.

[Wicket-user] How to attach thread
Dear all, within my Wicket application I'm using a self build process framework. I klick on a wicket button and a process starts running in an own thread. I want the process thread to take over the control of the wicket thread to e.g. build the gui, or change the current model of a component etc... (Actually I'm using the wizard component and want to combine/synchronize my own process steps with the wizard steps) But for now I receive this error message: caused by: wicket.WicketRuntimeException: there is no session attached to current thread Thread-51 at wicket.Session.get(Session.java:210) at wicket.Page.dirty(Page.java:338) at wicket.Page.componentStateChanging(Page.java:956) at wicket.Component.addStateChange(Component.java:2347) How can I attach the process thread to the wicket thread?
