Hi,

Sorry for the confusing.
Let me explain it more.
Let's suppose a simple CRUD page with a single DataTable and it's
dataprovider.
I need to refresh my datatable after a new item added.

So far I did it like this:

mw = new ModalWindow("modal");
mw.setWindowClosedCallback(new ModalWindow.WindowClosedCallback() {
                private static final long serialVersionUID = 1L;

                @Override
                public void onClose(AjaxRequestTarget target) {
                    dataTable.detachModels();
                    target.add(wm_bottom);
                }
            });

In my dataprovider I reloaded data when datatable (and dataprovider) got
detached.

    @Override
    public void detach() {
          myDAO.refreshData();
    }

and every other cases when datatable filtered or cleared and so one.
And at this point AjaxSelfupdatingBehaviour comes in the picture. I can't
rely on ondetach method anymore because it's fired in every second not just
when it needed.

I hope I need a different approach to refresh my data but I did not figure
it out so far.

Regards,  Sandor
