The problem is here: Grid doesn't know how to get the download
property (column) value to sort it, as you passed a null
PropertyConduit to the add() method.
You need to implement a PropertyConduit for and pass it to the add()
method. If Upload implements sortable, you don't need to
dModel.sortable(true);.
Here's one example for a PropertyConduit related to the manager
property (which is of type User) of the Project class:
public class ProjectManagerPropertyConduit implements PropertyConduit {
public <T extends Annotation> T getAnnotation(Class<T> annotationClass) {
return null;
}
/**
* @see org.apache.tapestry5.PropertyConduit#get(java.lang.Object)
*/
public Object get(Object instance) {
Project project = (Project) instance;
return project.getManager();
}
@SuppressWarnings("unchecked")
public Class getPropertyType() {
return User.class;
}
public void set(Object instance, Object value) {
Project project = (Project) instance;
project.setManager((User) value);
}
}
