Subject: Re: [Wicket-user] PageableDataView and column cells
Wow, that's a good one. I guess there are also others who
need it and facing the implementation (I couldn't have done
it this way) I think there is a need.
I was acutally thinking along the lines of implementing a
PageableOrderedRepeatingView and than nest another
OrderedRepeatingView.
What about having a default PageableOrderedRepeatingView -
glad there is autocompletition - which has a method
internalOnBeginRequest(int page, int startIndex, int size),
so you could do the above and maybe other things more easy by
hand. I don't have a real use-case - just a thought.
