Yes and no I fount out. I am embedding the deeplinks in the Rich Text Editor (RTE), but it handles them awkardly when entering, so I was totally confused. In the end it only works if the link in the RTE is relative: . However, in order to get this link in RTE, you have to specify the complete url in the linkbutton-popupwindow: e.g. http://localhost:8080/link/wiki/brpp
