Rik van der Kleij commented on WICKET-1766:
-------------------------------------------
OK, I got it. Some misperception on mine side about when isVisible() is called.
Johan, you mention that "the table is rendered again". I assume that within one
request rendering is always done one time, first security check and then
rendering.
Thanks Igor and Johan.
It's only a pity that in most cases clearing the cache is not necessary because
number of items is not changed. Normally size() queries the database so it will
increase the response time.

> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.3.4
> Environment: Ubuntu
> Reporter: Rik van der Kleij
> Assignee: Igor Vaynberg
> Priority: Minor
>
> Method size() of a data provider is invoked twice during one request. This
> happens when navigating to a next or latest page in a data table. During
> debugging I noticed that the onDetach() of AbstractPageableView is invoked an
> extra time. Implementations of size() normally query the database so it will
> slow down the performance.
