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
