Carl-Eric Menzel commented on WICKET-5821:
------------------------------------------
This is well-defined behavior. The order of submit methods is:
1. submitting button: onSubmit
2. form itself: onSubmit
3. submitting button: onAfterSubmit
Anything that needs to happen after the form's onSubmit can be done in
onAfterSubmit.
> Wicket calls AjaxButton#onSubmit() before Form#onSubmit()

> What is the point in firing AjaxButton#onSubmit() before Form#onSubmit()
> since form components are not yet properly configured?
> For example I have an complex component which consists of inner Form.
> In InnerForm#onSubmit() (which doesn't know about parent form) I'm setting up
> a complex model.
> {code}
> InnerForm#onSubmit(){
> Obejct modelObject = computeModelObjectFromManyFields();
> MyFormComponent.this.setModelObject(modelObject);
> }
> {code}
> Then I have an outer form in MyClass that contains MyFormComponent and an
> AjaxButton
> {code}
> protected void onInitialize() {
> form = new Form("form")
> form.add(new MyFormComponent("component", myComplexModel);
> form.add(new IndicatingAjaxButton("button", form){
> protected void onSubmit(AjaxRequestTarget target, Form<?> form)
> MyClass.this.formSubmitted(target);
> }
> });
> add(form);
> }
> protected void formSubmitted(AjaxRequestTarget target){
> doSomethingWithTarget(target);
> doSomething(myComplexModel.getObject());
> }
> {code}
> Unfortunatelly because AjaxButton#onSubmit() is called before
> InnerForm.onSubmit() in myComplexModel.getObject() I obtain null instead of
> computed object.
> Could you please fix this behaviour?
> Kind regards
