Perfect! Here is my PropertyConduit implementation public class DownloadPropertyConduit 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) { Upload upload = (Upload) instance; return upload.getName(); } @SuppressWarnings("unchecked") public Class getPropertyType() { return String.class; } public void set(Object instance, Object value) { Upload upload = (Upload) instance; upload.setName((String) value); } } --- En date de : Mer 1.7.09, Thiago H. de Paula Figueiredo <thiag...@gmail.com> a écrit : De: Thiago H. de Paula Figueiredo <thiag...@gmail.com> Objet: Re: Grid / sortable additionnal column À: "Tapestry users" <users@tapestry.apache.org> Date: Mercredi 1 Juillet 2009, 12h46 On Wed, Jul 1, 2009 at 8:39 AM, Francois Malet<francois_ma...@yahoo.fr> wrote: > Hello, Hi! > PropertyModel dModel= beanModel.add("download",null); 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); } } -- Thiago --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
