Re: Using AjaxCheckBox

2010-08-23 Thread Sven Meier 

Hi,

calling b.setOutputMarkupId(true) during Ajax request is too late. The 
HTML tag will not have a markup id, so nothing will be updated.


Call this method immediately after constructing the checkbox.

Regards

Sven

Hi,

I am trying to use AjaxCheckBox to update another checkbox model object when
this checkbox is clicked.

CheckBox b = new CheckBox(basicCreate,
 new ModelBoolean());

AjaxCheckBox a = new AjaxCheckBox(create,
 new ModelBoolean()) {

 private static final long serialVersionUID =
288634742710645609L;

 protected void onUpdate(AjaxRequestTarget target)
 {
 if (getModelObject()) {
 b.setModelObject(true);
 b.setOutputMarkupId(true);

 target.addComponent(b);
 }
 }
 };

So when checkbox a is checked, I want checkbox b to be checked as well.
But nothing happens. Am I doing something wrong?

Thanks,
Anna

Thanks, this fixed a problem. But I thought, it would give me an error
message, if I am trying to update a component that does not have
setOutputMarkupId(true) ?

Yes, you did call it before #addComponent():

b.setOutputMarkupId(true);
target.addComponent(b);

But Wicket doesn't keep track of *when* you called the method, i.e. 
before or after the Ajax request.

IIRC there should be an error message in the Ajax debug window.
