wicket will not sniff (call getModelObject()) on all the components when it just have a request to it.
It does ofcourse do that when rendering the page. Because the objects are needed then.

And that could be the thing that is different with ajax. Because you don't render the complete page.

Hi

 

I have some pages where I use Hibernate beans to hold the contents of my wicket componts, for example if I have a listbox then each dataItem is a Hibernate bean. There seem to be a performance problem with this when I have postbacks to the page, when using AJAX it does not seem to be a problem. Further more it does not seem to have anything to do with my wicket code(might be the way I've designed my wicket page(conceptually) though).

 

I have a kind of feeling that wicket on postbacks goes through all components and their childs, and sniffs them?

 

When testing without using hibernate the performance issue are gone. I guess a way to fix the issue is to instantiate POJO's from the hibernate beans to ensure that no hibernate listeners or whatever they use aren't transferred to GUI.

 

Whats your 2 cents on this?
