----------------------------------------
Summary: Improve generics for ListView: don't use wildcard for T
Key: WICKET-5931
URL: https://issues.apache.org/jira/browse/WICKET-5931
Project: Wicket
Issue Type: Improvement
Components: wicket
Affects Versions: 7.0.0-M5, 7.0.0-M6
Reporter: Martijn Dashorst
Fix For: 7.0.0
The generics for ListView<T> are that the model of each list item is not typed
as T but rather ? extends T. This makes the model for the ListView read only,
and you can't do anything with the list you get from the ListView.
For a ListView you care about the T so this should be pure, but you only care
about that the model for the ListView is some sort of List, so ? extends
List<T> is OK to use.
