Description

If Flash movie CS4/AS3 is added with Wicket/Ajax then AS3/ExternalInterface.call
does not return any value event it calls JavaScript functions, also ExternalInterface.objectID is null.

Suggestion is that wicket-ajax.js:268 (1.4.1) breaks IE+Flash/ExternalInterface:

// place all newly created elements before the old element
while(tempParent.childNodes.length > 0)

{ var tempElement = tempParent.childNodes[0]; >>>>>> tempParent.removeChild(tempElement); <<<<< parent.insertBefore(tempElement, element); tempElement = null; }

This "removeChild" breaks Flash/ExternalInterface in IE. If "removeChild" is removed then everything works fine.
