Problem with Populating collection in struts 2 Action

[Ke <js...@gmail.com>]

Hi, all,

I have the problem to populate collection from Struts 2 Action. I followed
the previous post from:
http://www.nabble.com/Populating-collection-in-struts-2-Action-properties-td8784718.html#a8784718

But it still does not work, I post my method here, any help will be
appreciated.

In my domain model:

public class Timesheet extends BaseObject {

       @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER,
mappedBy = "timesheet")
       private Set<Workday> workdays = new HashSet<Workday>();
.......
}

public class Workday extends BaseObject {


       @ManyToOne
       @JoinColumn(name = "timesheetId", updatable = false, insertable =
false)
       private Timesheet timesheet;
......
}

The JSP:

<s:textfield name="timesheet.startDate" theme="simple"
                                       id="timesheet.startDate"
cssClass="text medium" />
<s:iterator value="%{new int[14]}" status="stat">
<s:textfield theme="simple"
id="%{'timesheet.workdays['+#stat.index+'].date'}"
                              
name="%{'timesheet.workdays['+#stat.index+'].date'}" disabled="true"
size="10" maxlength="10"/>
       </s:iterator>
.......................

the generated html:
<input id="timesheet.workdays[5].date" type="text" disabled="disabled"
value="" maxlength="10" size="10" name="timesheet.workdays[5].date"/>

The TimesheetAction:
public class TimesheetAction extends BaseAction {

       private static final long serialVersionUID = 3449265559398237913L;

       private TimesheetManager timesheetManager;
       private List<Timesheet> timesheets;

       private Timesheet timesheet;
       private Long id;

       public void setId(Long id) {
               this.id = id;
       }

       public Timesheet getTimesheet() {
               return timesheet;
       }

       public void setTimesheet(Timesheet timesheet) {
               this.timesheet = timesheet;
       }

       public List<Timesheet> getTimesheets() {
               return timesheets;
       }

       public void setTimesheets(List<Timesheet> timesheets) {
               this.timesheets = timesheets;
       }

       public void setTimesheetManager(TimesheetManager timesheetManager) {
               this.timesheetManager = timesheetManager;
       }

       public String delete() {
               timesheetManager.remove(timesheet.getId());
               saveMessage("job deleted");
               return SUCCESS;
       }

       public String edit() {
               if (id != null) {
                       timesheet = timesheetManager.get(id);
               } else {
                       timesheet = new Timesheet();
               }
               return SUCCESS;
       }

       public String save() throws Exception {
               if (cancel != null) {
                       return "cancel";
               }
               if (delete != null) {
                       return delete();
               }
               SecurityContext securityContext =
SecurityContextHolder.getContext();
               User user = (User)
securityContext.getAuthentication().getPrincipal();


               System.out.println(timesheet.getStartDate());
               System.out.println(timesheet.getJobId());
               System.out.println(timesheet.getApprover().getId());
               System.out.println("--------" +
timesheet.getWorkdays().size());
               System.out.println("--------" + user);
               timesheet.setSubmitter(user);
               timesheet.setApprover(user.getSupervisor());
               timesheet.setSubmitDate(DateUtil.getToday().getTime());
               timesheet.setStatus("1");
               boolean isNew = (timesheet.getId() == null);
               timesheet = timesheetManager.save(timesheet);
               String key = (isNew) ? "timesheet added" : "timesheet
updated";
               saveMessage(key);
               if (!isNew) {
                       return INPUT;
               } else {
                       return SUCCESS;
               }
       }

       public String list() {
               timesheets = timesheetManager.getAll();
               return SUCCESS;
       }

}

Since  annotation is used  in the domain class, I think the properties file
is not necessary. But I still provide one, placed in the same folder with
Timesheet.class.

Timesheet-conversion.properties:
CreateIfNull_workdays=true
Element_workdays=com.absorbx.ctm.model.Workday

In my Action, the size of workdays is 0, you can see from my log file:
1
-2
--------0
--------com.absorbx.ctm.model.User@18e439a[username=user,enabled=true,accountExpired=false,credentialsExpired=false,accountLocked=false,Granted
Authorities: ,ROLE_USER]

Sorry for the mess code, is there any step I missed?


Best regards,
Ke CAI
