Wicket checkbox problem
Hi ,
I have problem getting the value from a check box.
I have something like this:
check = new CheckBox("check", Model.of(Boolean.TRUE));
add(check);
AjaxLink link = new AjaxLink("link")
{
@Override
public void onClick(AjaxRequestTarget target)
{
Boolean x = check.getModelObject();
System.out.println(x);
}
};
add(link);
The problem is that the check.getModelObject() returns true even if the
checkbox is unchecked.
I have tried adding check.modelChanged() method. Nothing changed.
Any suggestions ?Thx

Hi,
The problem is that AjaxLink doesn't send the new value to the server.
You need either AjaxCheckBox or CheckBox with
AjaxFormComponentUpdatingBehavior, or AjaxButton that will submit the
whole form.

Try a dynamic model
Boolean value ;
check = new CheckBox("check", new Model<Boolean>(){
public void setObject(Boolean object){ value=object}
public Boolean getObject(){return value}
});
//YOu may want to add an ajax onchange behaviour to the checkbox if you
want to value to be updated immediately you flip the checkbox.
AjaxLink link = new AjaxLink("link")
{
@Override
public void onClick(AjaxRequestTarget target)
{
System.out.println(value);
}
};
add(link);
Try something along those lines.
Josh.
