H Q T commented on WICKET-1349:
-------------------------------
I have this issue also - where I put javascript functions in a panel between
<wicket:head> tags in a panel markup. When I refresh that panel in IE it
doesn't work. I notice that when on IE the generated ajax response shown on the
wicket debugger shows "^" symbols. While on firefox the same action does not
generate javascript with the "^" symbol.
I solved this by putting my javascript into a separate .js file and put a
reference to it from the panel <wicket:head> tag instead of putting the js
script there. This works for me and the parent container gets refreshed on ajax
submit. I'm curious though how I can find out more why does the javascript
placed between <wicket:head> causes one output on IE and a different one on FF.

> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.3.1
> Environment: IE6 and IE7
> Reporter: Wen Tong Allan
> Assignee: Igor Vaynberg
>
> I have a page that uses AjaxFallbackDefaultDataTable (using
> SortableDataProvider ). The markup contains user-define javascript that I
> added. When I try to do some action (delete row) with the table, the page
> doesn't refresh in IE6 and IE7. I checked the Wicket Ajax Debugger and it
> displays:
> > > ERROR: Error while parsing response: Object required
> > > INFO: Invoking post-call handler(s)...
> > > INFO: invoking failure handler(s)...
> I also noticed that the user-define javascript that was returned by the ajax
> debugger was appended by "^". (See javascript below):
> // enable disable button.
> function setButtonState() {
> var formObj =
> eval(document.getElementsByName("contactListForm")[0]^);
> var state = anyChecked(formObj);
>
> document.getElementsByName("deleteContactsButton")[0]^.disabled = !state;
>
> document.getElementsByName("newContactGroupButton")[0]^.disabled = !state;
> document.getElementsByName("newEventButton")[0]^.disabled
> = !state;
> }
