Hello,

I've a smartform, a,d when I click to the K2Button, I want to modify some XmlFields ...

To do that, I open a connection and open the current process instance, but I don't success to write data on it... There is no error but in the reporting, there is no xml data...

Here is my code, can you help me?

the schema of my xmlfield is

Root
-> User
----> DisplayName
----> Login

.Value = doc.OuterXml;
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,
Ockert
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


Thanks a lot i just had to find the right worklist item.
