callback versioning issue

I have a use case that requires a non-wicket client side ajax invoked on my
page. The client side request comes after a form submit has been made on the
model. For the client side ajax, I'm using a AbstractDefaultAjaxBehavior and
using it's getCallbackUrl to preform a wicketAjaxGet with additional
parameters to update my page model. Functionally, this is working, but the
page state is reset to the default model when the client side ajax is
invoked, as if its a new page request. What is required in order for the
non-wicket invoke to be aware of the latest page version? 

Thanks in advance!

Re: Handle selection changing on Palette

HI,

have you tried with AjaxFormComponentUpdatingBehavior? As Palette's 
JavaDoc says:

" Ajaxifying the palette: The palette itself cannot be ajaxified because 
it is a panel and therefore does not receive any javascript events. 
Instead ajax behaviors can be attached to the recorder component which 
supports the javascript onchange event. The behavior should be attached 
by overriding newRecorderComponent() Example:

   Form form=new Form(...);
   Palette palette=new Palette(...) {
     protected Recorder newRecorderComponent()
     {
       Recorder recorder=super.newRecorderComponent();
       recorder.add(new AjaxFormComponentUpdatingBehavior("onchange") 
{...});
       return recorder;
     }
   } "

Hi Wicketers,

How can I handle selection changing on Palette? I would like to save 
item into database once it is selected from "Available" list.

Thanks,

I ended up figuring out the issue. It appears that the callback url needs to
be updated on ever state change, otherwise it uses a old version of the
model object.

You need to set a header, not a url param

Hi Igor,

Thanks for getting back to me. Can you provide an example? I tried adding
'&Wicket-Ajax=true to my wicketAjaxGet method, but still getting the same
result. 

Many Thanks

Brian

make sure your callback sets the Wicket-Ajax header so wicket knows
its an ajax request, otherwise it thinks you pressed refresh in the
browser.
