I tried that already. But I ran into the following problem:
Caused by: java.lang.ClassCastException: java.util.HashMap cannot be
cast to java.util.List
at
org.apache.wicket.markup.html.list.ListView.getList(ListView.java:174)
at
org.apache.wicket.markup.html.list.ListView.getViewSize(ListView.java:227)
at
org.apache.wicket.markup.html.list.ListView.onBeforeRender(ListView.java:538)
at org.apache.wicket.Component.beforeRender(Component.java:3037)
at
org.apache.wicket.MarkupContainer.onBeforeRenderChildren(MarkupContainer.java:1433)
... 28 more
The method-body:
public final List getList()
{
final List list = (List)getModelObject();
if (list == null)
{
return Collections.EMPTY_LIST;
}
return list;
}
So there is a need to use a List. I can't override getList() cause it's
final.
