AjaxFormComponentUpdatingBehavior after validation problem
Hello, I have such a problem with AjaxFormComponentUpdatingBehavior.
I have some DropDownChoice and a CheckBox on a Form. I need to make a change
to DropDown, when I click on CheckBox. But as I try to submit a Form, got
some error, and then click CheckBox DropDown doesn`t change. The code looks
like this:
DropDownChoice<SomeEnum> dropDownz = new
DropDownChoice<SomeEnum>("dropDownId",
Arrays.asList(SomeEnum.values()), new
EnumChoiceRenderer<SomeEnum>(this));
getGenericModelObject().setValues(SomeEnum.FIRSTVALUE);
CheckBox boxz = new CheckBox("BoxId");
boxz.add(new AjaxFormComponentUpdatingBehavior("onchange")
{
@Override
protected void onUpdate(AjaxRequestTarget target) {
if (boxz.getModelObject())
{
getGenericModelObject().setValues(SomeEnum.SECONDVALUE);
get("dropDownId").setEnabled(false);
target.addComponent(get("dropDownId"));
}
else
{
get("dropDownId").setEnabled(true);
target.addComponent(get("dropDownId"));
}
}
@Override
protected void onError(AjaxRequestTarget target, RuntimeException e) {
if (boxz.getModelObject())
{
getGenericModelObject().setValues(SomeEnum.SECONDVALUE);
get("dropDownId").setEnabled(false);
target.addComponent(get("dropDownId"));
}
else
{
get("dropDownId").setEnabled(true);
target.addComponent(get("dropDownId"));
}
super.onError(target, e);
}
});
Form form = new Form("formId", getGenericModel());
form.add(dropDownz);
form.add(boxz);
So as I said, after form validation, if errors occur, it won`t change
dropdown to SECONDVALUE, but sets it as setEnabled(false), why this happens?

Hello, here I renew this thread, because this problem is still cannot be
resolved.
So problem is that when you have AjaxFormComponentUpdatingBehaviour it works
fine, until that moment, when you try to submit your form. So when you get
error, that some kind of value is not as it is not supposed to be, all of
this AjaxBehaviour starts working kinda strange, it doesn`t update Models...
What can solve this problem?

Hello,
I think the problem is just that you're calling setValues on your
"genericModelObject", which is set as the compoundpropertymodel for your
form, but you're not adding the form back to the ajax response - with the
AjaxRequestTarget, you're only adding the component "dropDownId" to get
re-rendered into the page, not the form with the updated model. So, the
change made directly on the dropdown which is added to the ajaxRequestTarget
(calling setEnabled) is taking effect, but it's not finding the updated
model. It should work if you add:
target.addComponent(get("formId"));
Hope that helps,
-Evan

Form form = new Form("formId", getGenericModel());
form.add(dropDownz);
form.add(boxz);
So as I said, after form validation, if errors occur, it won`t change
dropdown to SECONDVALUE, but sets it as setEnabled(false), why this happens?

Hi Gytis,
If you add AjaxFormSubmitBehaviour to your checkbox it should work exactly as "Submit" button.

Hello, Michal,
Well, I`ve tried to make an AjaxFormSubmitBehaviour, but this doesn`t help,
in fact it is updating component, when you click "Submit" button, and I need
it updated, when clicking checkBox.
I`ve tried to add both Ajax behaviours, still doesn`t work. Wanted to add
some details on my code, for form submitting I use AjaxButton...

You can try using AjaxFormSubmitBehavior instead of AjaxFormComponentUpdatingBehavior.
Compare
org.apache.wicket.ajax.form.AjaxFormComponentUpdatingBehavior.onEvent(AjaxRequestTarget target)
and
org.apache.wicket.ajax.form.AjaxFormSubmitBehavior.onEvent(AjaxRequestTarget target)

Hi, Michal, I`ve tried AjaxCheckBox component, but problem is the same.
I even made Sytem.out.println() of what object is set in DropDown, it shows
that Object is SECONDVALUE, but still shows me FIRSTVALUE. Both dropDownz
and CheckBox OutputMarkupId set to true.

Hi,
Did you try using AjaxCheckBox instead of CheckBox with ajax behavior?
