well we have the new Wicket.Event thing you can use to install events. so really what you do is create a javascript variable, then install a 'domready' event that traverses the dom tree looks for formcomponents and adds an onfocus event. then we just need to make the ajax stuff aware of this.
see wicket-event.js and new method in iheaderresponse i have also been bitten by this, and recently there was a thread on the list about this as well. -igor On 2/19/07, Johan Compagner <[EMAIL PROTECTED]> wrote:
