AjaxRequestTarget on page open

[Paul Szulc]

This is going to be a lame question :) but I need help with this one.

I have DialogWindow (from visural-wicket library) that can be opened using
AjaxRequestTarget, below example that opens that dialog when ajax link is
clicked

        add(new IndicatingAjaxLink("addCostUp") {
            @Override
            public void onClick(AjaxRequestTarget target) {
                addCostDialog.open(target);
            }
        });

Is there a way to open that dialog when page is opened? You know, someone
is entering a page and dialog pops out? To open that dialog I need
AjaxRequestTarget. Is there a way to make page request ajax call just right
after the page was loaded?
