Robert Dahlström reopened WICKET-2676:
--------------------------------------
Added attachment that fails with a cast exception when run.
Either it is an indication of the issue, or I've misunderstood how to work with
generics & datatable.

> DataTable defines newCellItem to take IModel<T> but should really do
> IModel<IColumn<T>>

> Key: WICKET-2676

> Project: Wicket
> Issue Type: Bug
> Components: wicket-extensions
> Affects Versions: 1.4.5
> Reporter: Robert Dahlström
> Assignee: Igor Vaynberg
> Attachments: quickstart.zip

>
> The generics support in DataTable seems to not work entirely correctly:
> In the below the override for newCellItem actually gets a Model<IColumn>
> model, not a Model<T>, so perhaps it should be changed.
> do new AjaxFallbackDefaultDataTable<SomeClass>() {
> @Override
> protected Item<SomeClass> newRowItem(String id, int index,
> IModel<SomeClass> model) {}
> @Override
> protected Item<SomeClass> newCellItem(String id, int index,
> IModel<SomeClass> model) {
> // Model here is not Model<SomeClass> but Model<IColumn<SomeClass>>
> }
> }
