That means that some extra wicket code required to make it work. With this kind of change, I can make it work by handling some javascript only (no AjaxButton component is needed, I can trigger execution of the script whenever I want) this gives me some flexibility with no price. Also it doesn't affect the component behavior at all & will work as before.

> I have a use-case when an AjaxLazyLoadPanel needs to be loaded later then on 
> document "onready" js event (triggered later by some client-side event, like 
> click on some button). The way it is implemented right now, there is no way 
> to override AjaxLazyLoadPanel & change callback handling script. It would be 
> useful if instead of: 
> ================================= 
> add(new AbstractDefaultAjaxBehavior() { 
>   ... 
>   @Override 
>   public void renderHead(IHeaderResponse response) 
>   { 
>     super.renderHead(response); 
>     response.renderOnDomReadyJavascript(getCallbackScript().toString()); 
>   } 
>   ... 
> } 
> ================================= 
> it would be a protected method which would do the same thing: 
> ================================= 
> add(new AbstractDefaultAjaxBehavior() { 
>   ... 
>    @Override 
>   public void renderHead(final IHeaderResponse response) { 
>     super.renderHead(response); 
>     handleCallbackScript(response, getCallbackScript().toString()); 
>   } 
>   ... 
> } 
> protected void handleCallbackScript(final IHeaderResponse response, final 
> String callbackScript) { 
>   response.renderOnDomReadyJavascript(callbackScript); 
> } 
> =================================
