Get the VO from the AM

  MtlLotNumbersVOImpl vo= (MtlLotNumbersVOImpl)findViewObject("MtlLotNumbersVO1");
  MtlLotNumbersVORowImpl voi=(MtlLotNumbersVORowImpl)(vo.getCurrentRow());

  mLotDetailValuesHT.put("StatusId",voi.getStatusId());

First get the AM where your VO is attached, then get the VO from that AM.Get the RootAM and get all the VOs under that AM, using

writeLog(pageContext, "Room AM"+ pageContext.getRootApplicationModule());
String[] rootViewNames = pageContext.getRootApplicationModule().getViewObjectNames();
writeLog(pageContext," Length of the VOs from Rootm AM "+rootViewNames.length);
for (int j =0 ;j"+pageContext.getRootApplicationModule().getName() + " Child AMs=>"+ nestedAMArray.length,1);
OAApplicationModule currentAM = null;
currentAM = (OAApplicationModule)pageContext.getRootApplicationModule();
for(int i = 0; i < nestedAMArray.length; i++)
{
amName = nestedAMArray;
pageContext.writeDiagnostics(this,"Nested AM Name=>"+amName + "and amName.indexOf(objectivesAMName) "+amName.indexOf(objectivesAMName),1);
currentAM = (OAApplicationModule)pageContext.getRootApplicationModule().findApplicationModule(amName);
//Get the view names
String[] viewNames = currentAM.getViewObjectNames();
for (int i =0 ;i
