Re: [Wicket-user] Problem disabling PageMaps (Erik van Oosten)
Hello Erik, I'm using wicket 1.2. The pages themselves get the data from an object in the session every time it's needed. There are quite a few panels though that use models which in turn do have a reference to the object in the session. But I don't see a possibility of changing that somehow, the models need access to the object in several methods, and I can't use parameters to give it to the method directly. So I hope that's not where the problem is. Regards, Arjan Zwaan.

In addition, you can try to identify components that keep references to objects outside the page structure. In wicket 2 this will all be serialized so you need to keep your components lean.

Re: [Wicket-user] Problem disabling PageMaps
Well, as long as the data is in the session and not outside, you should be okay. Still, after you tried Igor's idea (the log4j debug parameter), you may want to take a look at the class LoadableDetachableModel. If you are interested, I made a small variation on LoadableDetachableModel that does not clear the data upon detach. Erik. A. Zwaan schreef: Hello Erik, I’m using wicket 1.2.

i don't know exactly when that property was made a setting now it is: if (Application.get().getDebugSettings().getSerializeSessionAttributes()) but that is now quite sometime so when it was exactly changed i don't know upgrade to the latest 1.2 then you can easily set that property. johan On 11/30/06, A.

Re: [Wicket-user] Problem disabling PageMaps
Hello Erik, Johan and karthik, Upgrading from Wicket 1.2 to 1.2.3 seems to have solved the problem. I do think I still have a bit of optimizing to do, but at least I'm not running into the OutOfMemoryError anymore. Thanks for your help and time. Greetings, Arjan Zwaan. - Take Surveys. Earn Cash.

i.e. in your case:

public Object getObject(Component component) {
return FinanSession.get().getMyFinanObject();
}
public void setObject(Object object, Component component) {
return FinanSession.get().setMyFinanObject(object);

Re: [Wicket-user] Problem disabling PageMaps (Johan Compagner)
I remember, in Wicket 1.2 it used to work out of a log4j setting which was changed to Application settings in the subsequent Wicket releases. Are you running Wicket 1.2 by any chance? If you are running Wicket 1.2 and have something like this - log4j.logger.wicket.protocol.http.HttpSessionStore=DEBUG in your log4j.properties, I think it will continue to serialize session attributes.
