Dialog Box is not replaced

[Tejash Tarun]

Hi,

In my page I have two dialog box say D1 and D2.

When clicking some link D1 should come, and it is happening. It is a
confirmation dialog box.

Now when I click ok button in D1 then D2 should be shown by replacing D1.

code is

D1.replaceWith(D2);
ajaxRequestTarget.add(D1);
ajaxRequestTarget.add(D2);

But nothing is happening on the screen.

Looking forward for some suggestions and answer.
Thanks in advance.

Regards,
Tejash
