I added AjaxFallbackButton("Cancel").setDefaultFormProcessing(false) to the
multipart form and when it is pressed the form is handled as well as the
button would have defaultFormProcessing=true.
It happens because request parameters does not contain the name of the
submitting button.
The magic is in the new code in wicket-ajax.js
// Submits a form using ajax.
// This method serializes a form and sends it as POST body.
submitForm: function(form, submitButton) {
if (this.handleMultipart(form)) {
return true;
}
var body = function() {
var s = Wicket.Form.serialize(form);
if (submitButton != null) {
s += Wicket.Form.encode(submitButton) + "=1";
}
return s;
}
return this.request.post(body);
},
I believe the problem is caused by handleMultipart(form) invocation.
submitForm function accepts submitButton parameter but does not passes it to
handleMultipart function.
Igor could you clarify that?
