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?
