RPC-call problem: it must have a zero-argument constructor or no constructors at all

[stockhausen]

Hello,

I have a RPC-call problem.

I get the following error: Screenshot

EntriesService.java

@RemoteServiceRelativePath("entries")
public interface EntriesService extends RemoteService {
    boolean updateAllEntries(long userid, EditorGrid<Entry> grid);
}

Entry.java

public class Entry extends BaseTreeModel implements IsSerializable {

    private static final long serialVersionUID = 1L;

    private long id;
    private String firstname;
    private String lastname;
    
    public Entry() {
        
    }

    public long getId() {
        return get("id");
    }

    public void setId(long id) {
        set("id", id);
    }
    
    public String getFirstname() {
        return get("firstname");
    }

    public void setFirstname(String firstname) {
        set("firstname", firstname);
    }

    public String getLastname() {
        return get("lastname");
    }

    public void setLastname(String lastname) {
        set("lastname", lastname);
    }

}

My Entry-class has implemented IsSerializable and a zero-argument constructor!!


Simple example ( eclipse project - 300K )

Whats the reason of this problem?


Thanks,

You try to send the grid widget object to the server. This cannot work.
