>             Project: Wicket
>          Issue Type: Bug
>          Components: wicket
>    Affects Versions: 6.6.0

>            Assignee: Sven Meier
>            Priority: Minor
>
> We are upgrading our wicket from 1.5.6 to 6.6.0
> and have broken one of our pages that uses ListDataProvider.
> The method getData() is called twice. Previously it was called once.
> Couple of questions. could I be doing something that calls getData()?
> Looking at the stack in debug. The first call looks like its driven by getViewSize whereas the second call is getItemModels.
> Thanks
> Mark
