Hi, The answer to your question is simple: component replacement over ajax needs to be able to "find" the old component so it can be replaced with new content. Since you set panel B to be invisible, it simply is not in the page, and therefore cannot be replaced.
Simple solution: if you want to replace an invisible component through AJAX, use http://wicket.apache.org/docs/1.4/org/apache/wicket/Component.html#setOutputMarkupPlaceholderTag(boolean) Component#setOutputMarkupPlaceholderTag . This will output an HTML tag which can be replaced by an AJAX call. Ofcourse you should also call setOutputMarkupId(true) so wicket generates an id with which it can locate the placeholder.
