>             Project: Tapestry 5
>          Issue Type: Bug
>          Components: tapestry-core
>    Affects Versions: 5.3.2, 5.3.4
>            Reporter: Paul Stanton
>              Labels: ajax, javascript, zone
>
> When a zone update occurs, the 'setupRender' is called for each component contained by that zone.
> If a script is added to ajaxResponseRenderer within the 'setupRender' method it is never executed on the page.
> eg:
> public class MyPage
> {
>     void onSomeEvent()
>     {
>         ajaxResponseRenderer.addRender(myZone); // myZone contains a MyComponent in the tml
>     }
> }
> public class MyComponent
> {
>     void setupRender()
>     {
>         if (request.isXHR())
>             ajaxResponseRenderer.addCallback(new JavaScriptCallback() { public void run(JavaScriptSupport javascriptSupport) {
>                     javascriptSupport.addScript("alert('here');");}});
>     }
> }
