ChoiceFilteredPropertyColumn
----------------------------
Key: WICKET-2770
URL: https://issues.apache.org/jira/browse/WICKET-2770
Project: Wicket
Issue Type: Improvement
Components: wicket-extensions
Affects Versions: 1.4.7
Reporter: Grzegorz Paniw
Priority: Trivial
ChoiceFilteredPropertyColumn contains filterChoices which was declared as
IModel<List<? extends Y>>. IMHO this is wrong way. Should be IModel<List<Y>>.
Why? Now if we want cast from model (f.e. HibernateListModel with type
Category) it's impossible without warnings. We must cast directly to IModel and
we can't cast to f.e. IModel<Category> or IModel<? extends Category>
(compilation error). See below:
(IModel) new HibernateListModel<Category>(Category.class).
So the better way is either put IModel<List<Y>> declaration or put
ChoiceFilteredPropertyColumn<T, ? extends Y> declaration.
Of course I look forward to comments to this issue.
