This is strange because when I look at the ajax debug window and compare the ajax responses of the two methods there isn't anything different other than rendering in a behavior causes the script to be rendered in a <header-contribution> as well as being rendered alongside the component. I think this is caused by the issue I mention in my latest email " IBehavior#rendered() is called twice when a component that has that behavior is rendered via AJAX".
If I prevent Wicket from calling IBehavior#rendered() (as mentioned in the above referenced mail) twice on a component during an AJAX request by commenting out the call to component.renderedBehaviors(); (AjaxRequestTarget.java line 524) then the _javascript_ is executed correctly in firefox, and that _javascript_ is not added as a <header-contribution> in the ajax response.
I don't understand why having the _javascript_ in a <header-contribution> as well as a <component> in the response would cause it not to execute correctly.

Okay. I'm making this up as I go along, so this could be the worst idea ever, but what about scanning a component's response for <script> tag, putting the contents in the AjaxRequestTarget as _javascript_s, and removing the <script> tag from the normal component output? From my reading of the source code, the evaluation of those scripts is controlled by the wicket ajax system (since a call to eval() is made when processing them).
I'm a Wicket/Web development newbie so I can't see far enough ahead to see potential problems with a solution like this.--On 10/15/06, Matej Knopp < [EMAIL PROTECTED] > wrote:Well, I'll try to look at it later today (or tomorrow). The problem is
that firefox executes the script "automatically", while in other
browsers we need to call the scripts in the fragment manually. So I
can't affect the order in which the scripts are bing called.
I'll see what I can do about it.
