Hi Igor, thank you for your suggestion, the lookup of the icon to display works fine. I now override ResourceReference.newResource()
Unfortunately, the lookup only works correctely the first time, i.e. when the Page is displayed. Subsequent Ajax updates and re-rendering of parts will always show the same (initially displayed) icon, independent of the current model state. Any suggestions on how to Ajax-enable this? Many thanks for your time, Erich ________________________________ Von: Igor Vaynberg <igor.vaynb...@gmail.com> An: users@wicket.apache.org Gesendet: Dienstag, den 29.
