> ListDataProvider calling getData() twice after upgrade to wicket6
> -----------------------------------------------------------------
>
> Key: WICKET-5937
> URL: https://issues.apache.org/jira/browse/WICKET-5937
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 6.6.0
> Reporter: Mark Christopher Newman
> 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
