Yes, without a placeholder tag for invisible components there is no DOM element for the Javascript to find for the Ajax replacement code when the (now visible) compopnent should be rendered. > I changed it to setOutputMarkupPlaceholderTag and this time it works.

When you work with toggling invisibility via Ajax you need to use the placeholder tag. The difference is that in the case where you don't output the placeholder, and invisible component's markup will not be found by other Javascript code traversing the DOM, which could have undesired effects based on assumptions about the element in question. - Tor Iver --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
