DVT: timeSelector

Question

Hi, would like to ask if it's possible to implement a time selector in a graph (line graph or bar graph) using the tabular data?
I'm having problem displaying the timeSelector for some reason...
managedBean:
  public List getLineGraphTabularData()
    ArrayList tabularData = new ArrayList();
    SimpleDateFormat sourceDateFormat =
      new SimpleDateFormat("yyyy-MM-dd-HH.mm.ss", getLocale());
    try
      Object[] entry1 =
      { sourceDateFormat.parse("2013-01-01-00.00.00"), "Jan", 1 };
      tabularData.add(entry1);
      Object[] entry2 =
      { sourceDateFormat.parse("2013-02-01-00.00.00"), "", 1 };
      tabularData.add(entry2);
      Object[] entry3 =
      { sourceDateFormat.parse("2013-03-01-00.00.00"), "", 1 };
      tabularData.add(entry3);
      Object[] entry4 =
      { sourceDateFormat.parse("2013-04-01-00.00.00"), "", 1 };
      tabularData.add(entry4);
      Object[] entry5 =
      { sourceDateFormat.parse("2013-05-01-00.00.00"), "", 1 };
      tabularData.add(entry5);
      Object[] entry6 =
      { sourceDateFormat.parse("2013-06-01-00.00.00"), "", 1 };
      tabularData.add(entry6);
      Object[] entry7 =
      { sourceDateFormat.parse("2013-07-01-00.00.00"), "", 1 };
      tabularData.add(entry7);
      Object[] entry8 =
      { sourceDateFormat.parse("2013-08-01-00.00.00"), "", 1 };
      tabularData.add(entry8);
      Object[] entry9 =
      { sourceDateFormat.parse("2013-09-01-00.00.00"), "", 1 };
      tabularData.add(entry9);
      Object[] entry10 =
      { sourceDateFormat.parse("2013-10-01-00.00.00"), "", 1 };
      tabularData.add(entry10);
      Object[] entry11 =
      { sourceDateFormat.parse("2013-11-01-00.00.00"), "", 1 };
      tabularData.add(entry11);
      Object[] entry12 =
      { sourceDateFormat.parse("2013-12-01-00.00.00"), "", 1 };
      tabularData.add(entry12);
    catch (ParseException e)
    return tabularData;
  }jsff page
                      <dvt:barGraph id="barGraph1" subType="LINE_VERT_ABS"
                                     shortDesc="test"
                                     tabularData="#{pageFlowScope.myManagedBean.lineGraphTabularData}"
                                     timeRangeMode="TRM_EXPLICIT" timeAxisType="TAT_DEFAULT" timeAxisInterval="CTAI_MONTH"
                                     timeRangeStart="#{pageFlowScope.myManagedBean.timeAxisStartDate}"
                                     timeRangeEnd="#{pageFlowScope.myManagedBean.timeAxisEndDate}">
                        <dvt:timeSelector explicitStart="#{pageFlowScope.myManagedBean.timeAxisStartDate}"
                                          explicitEnd="#{pageFlowScope.myManagedBean.timeAxisEndDate}"
                                          mode="EXPLICIT" fillColor="#849dff"
                                          borderColor="#1200ff"/>
                      </dvt:barGraph>any thoughts why the following code was not working?
Thanks.

After two days of testing and debugging I have found out several things:
<li> Setting the dates works until the manual change with the mouse in the browser.
<li> After the manual change, setting the dates does not work. It does not matter if you set it by bound bean attributes or in the TimeSelector object, every time the values are overwritten by the values from the manual change, so tehre is no change visible.
<li> There has to be some mechanism, where the values from the manual change are stored and reset to the timeselector object.
<li> There is a method called handleTimeSelectorEvent in class UIGraph, which seems to be a workaround/solution for my problem.
I have tested the method handleTimeSelectorEvent and set the values with this method additionaly:
public void cbButton1( ActionEvent actionEvent ) {
    // 2011-09-01
    Date startDate = new Date( 1314859410000L );
    // 2011-09-20
    Date endDate = new Date( 1316501010000L );
    lineGraph.handleTimeSelectorEvent( startDate.getTime( ), endDate.getTime( ) );
    TimeSelector timeSelector = lineGraph.getTimeSelector( );
    timeSelector.setExplicitStart( startDate );
    timeSelector.setExplicitEnd( endDate );
}No it works as expected, but there is one issue which sounds not that good. There is a remark in the javadoc documentation of the method:
>
For internal use only. Application developers should not use this
Handle a time selector event.
>
Is there some ACE expert who can tell if this is a good solution/workaround for the problem or shouldn't this method be called at all?
I know, the statement is there and clear, but is there an alternative workaround?
