Description

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');");}});
}
}
