Session expired drives me mad!
Hello everyone!
The session expired problem really drives me mad, because it's been couple of months or so since it started bothering me. Please advice me on what to do, because I'm despaired. Wicket tries to serialize every single class in my opinion.
I enabled the DEBUG of Wicket and messages like the following one are flooding the log. Here it is:
08-03-2010 17:30:03,445 ERROR org.apache.wicket.util.lang.Objects.objectToByteArray:1134 - Error serializing object class com.mycompany.myapp.ui.users.Users [object=[Page class = com.mycompany.myapp.ui.users.Users, id = 21, version = 0]]

I have had no problems with @SpringBean
Also try to use them like this:

This way you can avoid some mess that may occur in the future :)

Hello,
Well, I do use Spring Beans, and as shown in the stack trace, there is a field relation to the beans themselves. I don't think I can avoid it, do I? I create the beans by casting from the ApplicationContext.
Thank you,
Martin

Martin,
It looks like your page is holding on to Spring benas.
Are you using @SpringBean to inject Spring beans into your pages? That
way you would get a proxy to the beans so you don't need to worry
about them being serialisable.

Re: Session expired drives me mad!
Posted by Cemal Bayramoglu <jW...@cabouge.com>.
Martin,
It looks like your page is holding on to Spring benas.
Are you using @SpringBean to inject Spring beans into your pages? That
way you would get a proxy to the beans so you don't need to worry
about them being serialisable.

This is an ERROR!
You had to see it long time before enabling DEBUG.
Unless you disable everything but FATALs.

Wicket (or better: your model implementations) should not serialize your
entity objects. They are managed by spring orm, therefore use a specialized
LoadableDetachableModel in MyFormPanel that dynamically load your objects if
needed.
