Hello:
I have a simple search form , where some criteria refreshes the table based
on the db. I got it working with ListView, but im trying to use
ListDataProvider, I feel missing something:
class MyForm {
List myList;
MyDataView myDataView;
MyDataProvider myDataProvider;
public MyForm() {
@Override public void onSubmit() {
myList = refreshData(criteria);
//Question: How do I set this list into the myDataView or
myDataProvider ? I thought myDataView or the provider will auto pick it up,
because its a member variable and is a RefreshingView
}
//First time
myList = refreshData(defaultCriteria);
myDataView = new MyDataView("myDataView" , new MyDataProvider(myList));
add(myListView);
}
}
class MyDataView extends DataView {
public MyDataView(String id, IDataProvider provider) { super(id,
provider); }
@Override public void populateItem(Item item) { .... }
}
class MyDataProvider extends ListDataProvider {
public MyDataProvider(List list) {
super(list);
}
}
I looked at the example that uses ListView
http://cwiki.apache.org/WICKET/reading-from-a-database.html
<http://cwiki.apache.org/WICKET/reading-from-a-database.html>
With ListView it works fine if I do this in the method onSubmit()
myList = refreshData(criteria);
myListView.setList(myList);
But with DataView, I do not have a set method to reset the new list obtained
based on the criteria. The db returns correct data, but the page displays
the old data (no change). Neither do I see a method to set the new list in
the ListDataProvider.
I even tried adding a new view inside the onSubmit, but that doesnt work
either:
myDataView = new MyDataView("myDataView", new MyDataProvider(newList));
