Exception in TransactionBegin is multi user web environment

ChanKK — Mon, 30 Mar 2009 08:11:53 GMT

HI,
I hit the error as attached when I have 2 users perform same action at the same time. Any ideas?
Beside, may I know any special thing I need to take care of in web environment?

Please advice. Urgent!

[codesnippet]
public class LeavePersonalApplication : LeavePersonalApplicationBasePage
{
protected ResultSet Submit(ActionType actionType)
{
ResultSet result = new ResultSet();

this.LVELeaves.SubmitterAction = actionType;
this.LVELeaves.OwnerAction = actionType;

DocHelper docHelper = new DocHelper((IEmployeesBO)this.Owner,
(IEmployeesBO)this.Submitters,
(IDocumentsBO)this.LeaveAppUserControl.LVELeaves, Guid.NewGuid().ToString());

result = docHelper.Submit();

return result;
}
}

public class DocHelper
{
public DocHelper(VfsEmpInterface.IEmployeesBO documentOwner,
VfsEmpInterface.IEmployeesBO documentSubmitter,
VfsGenInterface.IDocumentsBO document)
{
if (documentOwner != null)
this.DocumentOwner = documentOwner;
else
throw new NullReferenceException("DocHelper: Document's Owner has Null Reference during Initialization.");

if (documentSubmitter != null)
this.DocumentSubmitter = documentSubmitter;
else
throw new NullReferenceException("DocHelper: Document's Submitter has Null Reference during Initialization.");

if (document != null)
this.Document = document;
else
throw new NullReferenceException("DocHelper: Document has Null Reference during Initialization.");

this.TransactionKey = new Guid().ToString();

this.document.SysDocId = SysDocBO.SysDocId;
}

public DocHelper(VfsEmpInterface.IEmployeesBO documentOwner,
VfsEmpInterface.IEmployeesBO documentSubmitter,
VfsGenInterface.IDocumentsBO document,
string transactionKey): this(documentOwner, documentSubmitter, document)
{
this.TransactionKey = transactionKey;
}

public VfsGenBO.ResultSet Submit()
{
VfsGenBO.ResultSet result = new VfsGenBO.ResultSet();
VfsWfBO.TasksBO task = new VfsWfBO.TasksBO();

BusinessLayerExtension.TransactionBegin(VfsWfHelper.WfHelper.WORKFLOW_DSKEY, this.TransactionKey, IsolationLevel.ReadCommitted);
BusinessLayerExtension.TransactionBegin(ESSLVE_DSKEY, this.TransactionKey, IsolationLevel.ReadCommitted);
BusinessLayerExtension.TransactionBegin(HRMSLVE_DSKEY, this.TransactionKey, IsolationLevel.ReadCommitted);

Well, without having my hands on this code it is going to be next to impossible for me to debug and give a straight answer. But one thing that I might suggest trying is one of the following:

Give a unique name to the transaction name. For example, use a System.Guild.NewGuid.ToString() or something to ensure a unique transaction name.
If that doesn't work, then turn off transactions to make sure that this is your point of failure.
