Re: replace Panel inside a Form
the problem is you replace it but do not update the reference so next time
the onclick runs it calls replacewith on an old reference. it is a common
mistake.
EinsatzPanel newPanel = new EinsatzPanel("einsatzPanel", ein);
newPanel.setOutputMarkupId(true);
einsatzPanel.replaceWith(newPanel);
einsatzPanel=newPanel; < what you are missing

Re: replace Panel inside a Form
Hi Benjamin,
where is the Panel einsatzPanel defined?
Maybe it helps defining it as a Class property?
Kind regards

Here is the code:

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

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);
}
});
