Re: replace Panel inside a Form

[Florian Sperber]

Hi Benjamin,

where is the Panel einsatzPanel defined?

Maybe it helps defining it as a Class property?


Kind regards

Hi,
I am trying to replace a Panel, which is inside a Form, which is inside a
Page, which is inside a ModalWindow.
The first time it works fine, but when I want to replace it a second time,
the Panel has no parent.

Here is the code:

listItem.add(new AjaxButton("pflege", MitarbeiterForm.this) {

                        @Override
                        protected void onSubmit(AjaxRequestTarget target,
Form form) {
                            EinsatzPanel newPanel = new
EinsatzPanel("einsatzPanel", ein);
                            newPanel.setOutputMarkupId(true);
                            einsatzPanel.replaceWith(newPanel);
                            target.addComponent(newPanel);
                        }
               });

An here is the Error:

2007-08-24 14:53:18,681 ERROR [http-8080-Processor24]

I don´t know why it only works one time.

Thanks for any help in advance,

Benjamin
