AjaxRequestTarget + add component

[Ivoneta <ie...@gmail.com>]

Hi.

I have two panels inside a webPage.
In the first Panel I have a form with a ajax button. When I submitted de
form the two panels should be replace and target.
 
In the code I replace the firstPanel, them I add to te target this: 
target.addComponent(panel);
I do the same for the second panel.
So, I have two "target.addComponent(panel)"; , and I get an error (Null
pointer exception).

I wonder if it's not possible have two  "target.addComponent(panel)" in the
same place?

Please post the NPE stack trace, as well as what version of Wicket you are
using.  It would be good to post the code from your ajax button, too.
