Hi all
Here's just newbie's quesion on using PageableListView.
I'm trying to use PageableLiveView in my project. But it doesnt work. The
following is the error I got. As I can see, I do have that room_type
component in the html file. It just doesnt work.
Since I dont understand how PageableListView works, I just mimic the library
example on the wicket website.
Now I need this to show my search result and I dont know any other ways to
make pageable list. This is quite urgent to me. I need it to finish my
assignment.
Could any buddy please help me out???? Many thanks..

WicketMessage: The component(s) below failed to render. A common problem is
that you have added a component in code but forgot to reference it in the
markup (thus the component will never be rendered).
1. [Component id = room_type, page =
com.smartbooking.wicket.page.RoomResultListPage, path =
1:rooms:0:description:room_type.Label, isVisible = true, isVersioned = true]
2. [Component id = room_type, page =
com.smartbooking.wicket.page.RoomResultListPage, path =
1:rooms:1:description:room_type.Label, isVisible = true, isVersioned = true]
