Persistence problems

Question

Hello. I have made myself a web app using Java Server Faces which I am running on Glass Fish V2.
The problem that I am having is that while the program complies and runs without throwing any exceptions. My entities are not beeing saved to the database when I call the persist() method on them. The primary key of the entity objects (which is set to auto generate) is updated after the call to persist(), and the sequence database table is also updated. But no data is entered in to the database table for the entity object.
My app reads data from the database that I have inserted via SQL commands by running Queries made in the Java persistencve query lanuage and returns entity objects as you would expect.
Here is the entity object I am trying to save.
@Entity
@NamedQueries({
@NamedQuery(name="getTimeSheetsBetween",
            query="Select ts From TimeSheet ts Where ts.startDate >= :startDate AND ts.endDate <= :endDate"),
@NamedQuery(name="getTimeSheetsFor",
            query="Select ts From TimeSheet ts Where ts.timeSheetUser = :user")})
public class TimeSheet implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;
    @ManyToOne
    private TimeSheetUser timeSheetUser;
    @Temporal(TemporalType.DATE)
    private Date startDate;
    @Temporal(TemporalType.DATE)
    private Date endDate;
    private boolean signedOff;
    @OneToMany(cascade=CascadeType.ALL)
    private List<TimeSheetDay> timeSheetDays;
    public TimeSheet(){
    public TimeSheet(TimeSheetUser pUser, Calendar pStartDate, Calendar pSettingsStartDate, int pLength){
        Calendar testEndDate = (GregorianCalendar) pSettingsStartDate.clone();//modifications to objects passed as method parameters are not reverted after the method is finished
        Calendar testStartDate = (GregorianCalendar) pSettingsStartDate.clone();//so we create new date values to change which will not effect the pSettingsStartDate object
        testEndDate.add(Calendar.DAY_OF_MONTH, pLength);
        while(!(pStartDate.after(testStartDate) && pStartDate.before(testEndDate))){
            testStartDate.add(Calendar.DAY_OF_MONTH, pLength);
            testEndDate.add(Calendar.DAY_OF_MONTH, pLength);
        }//not sure if this is the best way to work this out. Refacter later
        startDate = testStartDate.getTime();
        endDate = testEndDate.getTime();
        signedOff = false;
        timeSheetUser = pUser;
        timeSheetDays = new ArrayList(pLength);
        for(int counter = 1; counter <= pLength; counter++){
            TimeSheetDay day = new TimeSheetDay(testStartDate.getTime());
            timeSheetDays.add(day);
            testStartDate.add(Calendar.DATE, 1);
    Here is the method that saves data

Hi,
We are using JDeveloper 11.1.1.6. We have enabled the MDS on this setup.
Though its working fine with all the defined components , its not working for af:panelsplitter.
Can you please update if MDS is working fine with af:panelsplitter in JDeveloper 11.1.1.6?
