Hi,
                              I am using following code to add new
row in repeating table.

IXMLDOMNode Item1 = thisXDocument.DOM.selectSingleNode("my:myFields/
my:group6/my:group7/my:txtItem1");

Item1.text="";

IXMLDOMNode Desc1 = thisXDocument.DOM.selectSingleNode("my:myFields/
my:group6/my:group7/my:txtDesc1");

Desc1.text="";

IXMLDOMNode CreatedDt1 =
thisXDocument.DOM.selectSingleNode("my:myFields/my:group6/my:group7/
my:txtCreatedDt1");

CreatedDt1.text=dtServer.ToString();

IXMLDOMNode Planed1 = thisXDocument.DOM.selectSingleNode("my:myFields/
my:group6/my:group7/my:dtPlaned1");
Planed1.text="";

IXMLDOMNode Status1 = thisXDocument.DOM.selectSingleNode("my:myFields/
my:group6/my:group7/my:cboStatus1");
Status1.text="";

IXMLDOMNode ClosureDt1 =
thisXDocument.DOM.selectSingleNode("my:myFields/my:group6/my:group7/
my:dtClosureDt1");

ClosureDt1.text="";

IXMLDOMNode ClComments1 =
thisXDocument.DOM.selectSingleNode("my:myFields/my:group6/my:group7/
my:txtClComments1");

ClComments1.text="";

thisXDocument.View.ExecuteAction("xCollection::insert","group7_61");

But i got following error:

System.NullReferenceException
Object reference not set to an instance of an object.
