AW: Ajax URL encoding and &

[Stefan Lindner]

I want to trigger a method of a wicket component from  a self written 
JavaScript function e.g.
 
     <script>
          onClick....call 'WicketAjax
     </script>
 
So I create an AjaxBehavior that extends AbstractAjaxBehavior oder 
AbstractDefaultAjaxBehavior and add it to a Wicket Component.
 
My class implements the onComponentRendered method jut like this 

     String func = "function() { wicketAjaxGet('" + this.getCallbackUrl() + 
"'); }"

     RequestCycle tequestCycle = RequestCycle.get();

     Response response = tequestCycle.getResponse();

     response.write(builder.toScriptTag());

And because getCallbackUrl does not escape the & the raw & is rendered into the 
page. This is nor problem for functionality (everything works well) but it 
makes html debugging hard because of the validation errors caused by &.

Now I can do the encodeing by myself but then the wicketAjaxGet fires the 
respond method wit all parameters named "&amp;paramName".

Now I can call 

     getComponent().getRequest().getParameter("&amp;paramName")

in the respond method but this looks strange for me.

If this is the intended way to do such things I will do them so.

ahh yes it is the ajax event behavior that is altered
(thats an behavior that is attached to events so on attributes like onclick)

which behavior do you exactly use and where is it exactly inserted in?
