Didn't do decent troubleshooting but...

First try with simpler code like a hardcoded display name and login.
Second, try the Update() method of the Process Instance after you've set the XML field.

Hope this helps,

That's it...

The update() method did the job...

I have used this code and modified it a bit to get my own schema i.e.

- <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<Company CompanyName="Accountants On Call" CompanyID="9" Selected="false" />
<Company CompanyName="Afgri Operations Ltd" CompanyID="43" Selected="false" />
<Company CompanyName="BAD" CompanyID="22" Selected="false" />
</xs:schema>

My problem is when I read it back with the following code :

Connexion = new SourceCode.K2ROM.Connection();
Connexion.Open(ConfigurationSettings.AppSettings["PlanServer"]);
K2Instance = Connexion.OpenProcessInstance(int.Parse(Request.QueryString["sn"].Split(',')[1]));
XmlNodeReader reader = null;

XmlDocument doc = new XmlDocument();
doc.LoadXml(K2Instance.XmlFields["IntCompany"].Schema);


XmlNodeList NodeList = null;

NodeList = doc.DocumentElement.GetElementsByTagName("Company");

foreach(XmlNode CompanyNode in NodeList)
{
reader = new XmlNodeReader(CompanyNode);
reader.Read();

ListItem newItem = new ListItem(reader.GetAttribute("CompanyName"),reader.GetAttribute("CompanyID"));
if (reader.GetAttribute("Selected") == "true")
newItem.Selected = true;
else
newItem.Selected = false;
}
reader.Close();

I do not get any data back can anyone help here please. I am new to using XML so please forgive me if I am totally lost here.

You must use the value property to bring back the data. Have a look at the example:

        'Put user code to initialize the page here
        Dim cn As New K2ROM.Connection
        Dim WLItem As K2ROM.WorklistItem
        Dim WList As K2ROM.Worklist
        Dim sn As String
        Dim ProcessInstanceID As String
        Dim redirectURL As String
        Dim PrevComments As String

        Try
            If Not IsPostBack Then

                sn = Request.QueryString("sn").ToString

                cn.Open(sn.Split(",")(0))

                WList = cn.OpenWorklist("ASP")

                ProcessInstanceID = sn.Split(",")(1)

                For Each WLItem In WList
                    Dim WListProcessID As String = WLItem.ProcessInstance.ID.ToString

                    If WListProcessID = ProcessInstanceID Then
                        WLItem.Open()
                        With WLItem

                            lblTopic.Text = "Topic to discuss: " & .ProcessInstance.DataFields("Topic").Value
                            PrevComments = .ProcessInstance.XmlFields("PrevComments").Value


                            Dim DS As New DataSet
                            Dim FS As FileStream

                            If PrevComments <> "" Then
                                Dim XmlDoc As New System.Xml.XmlDocument
                                XmlDoc.LoadXml(PrevComments)
                                XmlDoc.Save(Server.MapPath("K2.xml"))

                                FS = New FileStream(Server.MapPath("K2.xml"), FileMode.Open, FileAccess.Read)
                                Dim Reader As StreamReader
                                Reader = New StreamReader(FS)
                                DS.ReadXml(Reader)
                                FS.Close()

                                Dim View As DataView
                                View = New DataView(DS.Tables(0))
                                DGComments.DataSource = View
                                DGComments.DataBind()
                            End If

                        End With

                        Exit For
                    End If
                Next

                cn.Close()

            End If

        Catch ex As Exception
            redirectURL = ConfigurationSettings.AppSettings("WebRoot") & "Error.aspx?Error=" & ex.Message
            Response.Redirect(redirectURL)
        End Try
