Hi Matt;
Make a dynamic dataprovider as follows:
public abstract class UserDataProvider extends SortableDataProvider<User> {
public UserDataProvider(){
setSort("id", SortOrder.ASCENDING);
}
public Iterator<User> iterator(int start, int count) {
return User.getItems(getSearchParam()).iterator() ;
}
public IModel<User> model(User user) {
return new Model<User>(user);
}
public int size() {
return User.getItemCount(getSearchParam());
}
public abstract String getSearchParam();
}
Not the abstract method for getting the filtering parameter.
Then use it like this:
UserDataProvider dp = new UserDataProvider() {
@Override
public String getSearchParam() {
return searchParam
}
};
The search parameter is recalculated everytime the table is refreshed.
Hope you get the idea.
Josh.
