Now I have add an encoder
<form t:type="form">
<t:label for="members"/>:
<t:select t:id="members" value="membersName" model="MemberSelectModel"
encoder="wholeSaleMemberEncoder" />
<t:submit value="save"/>
</form>
public class WholeSaleMemberEncoder implements
ValueEncoder<WholeSaleMember>, ValueEncoderFactory<WholeSaleMember> {
@Inject
private WholeSaleMemberDao wholeSaleMemberDao;
@Inject
private DatabaseDao databaseDao;
public String toClient(WholeSaleMember value) {
// return the given object's ID
return String.valueOf(value.getId());
}
public WholeSaleMember toValue(String id) {
// find the color object of the given ID in the database
return (WholeSaleMember) databaseDao.load(Long.parseLong(id),
WholeSaleMember.class);
}
public ValueEncoder<WholeSaleMember> create(Class<WholeSaleMember>
type) {
// TODO Auto-generated method stub
return this;
}
}
public class CreateWMemberTruck {
@Inject
private WholeSaleMemberDao wholeSaleMemberDao;
@Property
private WholeSaleMemberEncoder wholeSaleMemberEncoder;
@Property
private SelectModel memberSelectModel;
@Property
@Inject
private SelectModelFactory selectModelFactory;
@Property
private WholeSaleMember membersName;
void setupRender() {
// invoke my service to find all colors, e.g. in the database
List<WholeSaleMember> members =
wholeSaleMemberDao.getWholeSaleMembers();
// create a SelectModel from my list of colors
memberSelectModel = selectModelFactory.create(members, "fName");
}
void onSuccess() {
System.out.println("\n\n\n"+membersName.getId()+"\n\n\n\n");
}
}
Now t:select is not populated, that page gives an exception
org.apache.tapestry5.internal.services.RenderQueueException
Render queue error in
