Interactive Gantt chart - how to receive updated XML after user changes

Question

Hello,
I failed to receive changed XML after user updates.
I've constructed following example:
Created context attribute of type XSTRING, binded it to the "dataSource" property of the Gantt chart control.
I pass following XML to the control:
<?xml version="1.0" encoding="iso-8859-5" ?>
<SAPJNetData version="1.0">
<Application type="GANTT" version="1.0" />
<TypeRepository version="1.0" href="/SAP/BC/WebDynpro/SAP/ZT_INV_WDR_TEST_GANTT/gantPR02P00086_3_tr.xml" />
<UserInterface version="1.0" href="/SAP/BC/WebDynpro/SAP/ZT_INV_WDR_TEST_GANTT/gantPR02P00086_3_ui.xml" />
<Graph type="Gantt.Graph" version="1.0">
<rows>
  <row id="001" />
  <row id="002" />
  <row id="003" />
  </rows>
<dates timeZone="GEurope/Berlin" locale="de_DE" format="dd.MM.yyyy" dateEnd="20.01.2010">
  <section date="01.01.2010" unit="DAY" unitSize="20" />
<calendarItem id="Cal.1stDayInMonth">
  <repetition unit="MONTH" />
  </calendarItem>
<calendarItem id="Cal.1stDayInWeek">

  </calendarItem>
  </dates>
<view>
  <viewpos date="01.01.2010" />
  </view>
<chart id="Dummy">

  </cols>
<header>
  <header width="30" />
  <label colid="TREE" width="250">Этап</label>

  </row>
<row>
  <header>2</header>
  <tree parentRow="001">Subitem 1</tree>
  <label>01.01.2010</label>
  <label>10.01.2010</label>
  </row>
<row>
  <header>3</header>
  <tree parentRow="001">Subitem 2</tree>
  <label>11.01.2010</label>
  <label>20.01.2010</label>
  </row>
  </table>
<graph>
<view>
  <backColor type="White" />
  </view>
<node id="001" type="Gantt.CProjects.SummaryNode" rowID="001">
<dates>
  <date>01.01.2010</date>
  <date>20.01.2010</date>
  </dates>
  </node>
<node id="002" type="Gantt.CProjects.Node" rowID="002">
<dates>
  <date>01.01.2010</date>
  <date>10.01.2010</date>
  </dates>
  </node>
<node id="003" type="Gantt.CProjects.Node" rowID="003">
<dates>
  <date>11.01.2010</date>
  <date>20.01.2010</date>
  </dates>
  </node>
  </graph>
  </chart>
  </Graph>
  </SAPJNetData>
Then I run my example application, press standard "Save" button in Gantt chart control.
After that my XML in context changes, but it's incorrect. There is no <graph> tag at all - this tag should contain all significant parameters of the chart.
The resulting XML below:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<SAPJNetData build="9295" date="04-Aug-2010 10:19:13" host="localhost" version="1.1247">
<Application type="GANTT" version="1.0"/>
<TypeRepository href="/SAP/BC/WebDynpro/SAP/ZT_INV_WDR_TEST_GANTT/gantPR02P00086_3_tr.xml" version="1.0"/>
<UserInterface href="/SAP/BC/WebDynpro/SAP/ZT_INV_WDR_TEST_GANTT/gantPR02P00086_3_ui.xml" version="1.0"/>
<GraphGantt version="1.1247"/>
</SAPJNetData>
All the chart in fact has completely disappeared. There is nothing left but file header.
The question: How to get XML with all user changes back from the Gantt chart control?
