Question

I am trying to implement a generic search form/panel in Wicket. The form should allow searches in several fields in an Entity (using the DAO pattern) in order to filter the output of a ListView or a DataView. What is the best way to do this? I’ve thought of doing this using an extended DataProvider but I haven’t really seen any real example.

Did anyone implemented such a thing? Some pointers would be nice.

edit

An aditional question that might help set the direction of the answers:

• Do Wicket Models combine well with DataProviders?

Answer 1

You can extend IDataProvider with search methods:

    public interface SearchableDataProvider<T> extends IDataProvider<T> {

    public void setSearchQuery(String... query);

    public void clearSearchQuery();


    @Override
    public Iterator<? extends T> iterator(int first, int count);


    @Override
    public int size();

}

And implement this interface in your EntityManagers such as UserManager, ArticleManager or AccountManager.
