Rik van der Kleij commented on WICKET-1766:
-------------------------------------------
Our code does not tie visibility to rowcount();
We are adding a navigation toolbar to the data table. The navigation toolbar
overrides isVisible() and invokes indirectly getRowCount(). That also
corresponds with mine experience that size() was invoked twice when using the
navigation links.
> Method size() of a data provider is invoked twice.

> URL: https://issues.apache.org/jira/browse/WICKET-1766
> 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.
