How can I change the value of a text box within my document?

When I do the following:

IXMLDOMNode nNextAction = thisXDocument.DOM.selectSingleNode("my:myFields/my:NextAction");
nNextAction.text = "blah";

then the value does not stay changed when the document is stored/submitted.

When I do:

nNextAction.nodeValue = "Review";

then I get a security exception :-/

You probably need to remove the xsi:nil attribute. I use this helper function:

IXMLDOMNode nNextAction = thisXDocument.DOM.selectSingleNode("my:myFields/my:NextAction");
removeNil(nNextAction).text = "blah";

public IXMLDOMNode removeNil(IXMLDOMNode n)
{
	//Determine whether the xsi:nil attribute is set for this
	//element. If so, remove the xsi:nil attributes so that
	//the value can be set.
	if (n.selectSingleNode( "@xsi:nil" ) != null)
		n.selectSingleNode( "@xsi:nil" ).text = "false";				
		
	// return the node for convenience
	return n;
}

Hope this helps!

OK, but when you have to remove or reapply the xsi:nil attribute in a Changing event handler, the Changing event fires the other time. Is there anything like DisableEventFiring around to help with that?
