ok, and thank you, but why do i have to use this:
BookmarkablePageLink(item,"linkTo",link.getLinkTarget(),link.getParams());
and not using it instead like this:
BookmarkablePageLink(this,"linkTo",link.getLinkTarget(),link.getParams());
in
ListView(this, "tabList", tabList) {
> protected void populateItem(ListItem item) {
i mean, the markup is present in this not in item, isnt it??
Best Regards,
Korbinian
