The Java – wicket check box automatically submits its changed value to the domain object

What is the cleanest way I can make a check box automatically submit the form it belongs to in wicket? I don't want to include a submit button at all This check box is supported by a Boolean field (in this case, account) in the domain object

Simplified example of omitting irrelevant parts:

EntityModel<Account> accModel = new EntityModel<Account>(Account.class,id);

PropertyModel<Boolean> model = new PropertyModel<Boolean>(accModel,"enabled");
Check@R_507_2419@ check@R_507_2419@ = new Check@R_507_2419@("cb",model);
Form form = new Form("form");
form.add(check@R_507_2419@);
add(form);

HTML：

<form wicket:id="form" id="form" action="">
    <input wicket:id="cb" type="check@R_507_2419@" />
</form>

Edit: to clarify, my goal is to change the field of the domain object (– > value in the database) when the check box is switched Any (clean, simple) way to achieve this will be fine I don't know if you really need this form

Solution

Just override the wantonselectionchanged notifications () of all check boxes, even if it doesn't override onselectionchanged () – it seems to do what I want

In this way, you do not need the form on the Java side, so the above code will become:

EntityModel<Account> accModel = new EntityModel<Account>(Account.class,id);

add(new Check@R_507_2419@("cb",new PropertyModel<Boolean>(accModel,"enabled")){
    protected boolean wantOnSelectionChangedNotifications() {
        return true;
    }
});

Feel free to add a better solution or better explain what happened with this approach!

Editor: check carefully. I guess the method's Javadoc makes it clear why it does what I want (emphasize my):
