Re: Grid / sortable additionnal column

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);
    }


}

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);

    }

}
