Hello Maurice, We just (almost) implemented this component (as I wrote in response to Erik's post), but we're are now struggling with not processing the form and retaining user input
other than that I have the same wondering, if I submit only the inner form, will the browser send the whole form, or will the AjaxSubmitLink only submit the part I'm interested in? It's quite important because I will have fileiupload fields in the the outer form, so then adding an item to this listview (and sending this little form) will cause the browser to send the whole form with heavy files ... that would be absurd how does it work in wicket 1.3.1? or do I have to get a sniffer to be sure? regards Wojtek 2008/3/5, Maurice Marrink <[EMAIL PROTECTED]>: > Actually AjaxFormComponentUpdatingBehavior accomplishes the desired > behavior without submitting the entire form.
