11:15 a.m.
I use sem-gem to generate a new eclipse project (seam setup, seam new-project), then I
added a new action testdnd to perform drag and drop operation.
This is the code
import java.util.ArrayList;
| import java.util.List;
|
| import javax.ejb.Stateless;
| import org.jboss.seam.annotations.Name;
| import org.jboss.seam.annotations.In;
| import org.jboss.seam.annotations.Logger;
| import org.jboss.seam.log.Log;
| import org.jboss.seam.core.FacesMessages;
| import org.ajax4jsf.dnd.event.DropEvent;
|
| @Stateless
| @Name("testdnd")
| public class TestdndBean implements Testdnd {
|
| @Logger private Log log;
|
| @In FacesMessages facesMessages;
|
| public void testdnd()
| {
| //implement your business logic here
| log.info("testdnd.testdnd() action called");
| facesMessages.add("testdnd");
| }
|
| public void processDrop(DropEvent dropEvent) {
| System.out.println("PROCESSDROP CALLED");
| }
|
| public List getValori(){
| ArrayList al=new ArrayList();
| al.add("a");
| al.add("b");
| al.add("c");
| return al;
| }
| //add additional action methods
|
| }
here the local interface
| import java.util.List;
| import org.ajax4jsf.dnd.event.DropEvent;
| import javax.ejb.Local;
|
| @Local
| public interface Testdnd {
|
| //seam-gen method
| public void testdnd();
|
| public void processDrop(DropEvent dropEvent);
|
| public List getValori();
| }
and here the page that use the bean

If I use the method processDrop without the DropEvent parameter all works well, but using
the previous code I obtain this error :

Even if in this simple example the method processDrop don't use the DropEvent
parameter I am interested to use it for some check operation.
I have used the latest version of seam from cvs (downloaded today).
Please help me!!
