Typemock: System.NotSupportedException: Cannot dynamically create an instance of System.Void.

Had a problem mocking a call to SPWorkflowActivationProperties.Item today. Turns out to be a bug in the TypeMock library.

Problematic unit test

[Test, Isolated]
        public void PublishToExternalDocumentLibrary_Calls_CopyTo_Correctly()
            ApprovalWorkflow approvalWorkflow = Isolate.Fake.Instance<ApprovalWorkflow>(Members.CallOriginal, ConstructorWillBe.Called);
            SPWorkflowActivationProperties activationProperties = Isolate.Fake.Instance<SPWorkflowActivationProperties>(Members.CallOriginal, ConstructorWillBe.Called);
            SPListItem item = Isolate.Fake.Instance<SPListItem>();

            Isolate.WhenCalled(() => approvalWorkflow.PublishWhenComplete).WillReturn(true);
            Isolate.WhenCalled(() => approvalWorkflow.PublishDocumentLibraryUrl).WillReturn(ExternalDocumentLibraryUrl);
            Isolate.WhenCalled(() => approvalWorkflow.WorkflowActivationProperties).WillReturn(activationProperties);
            Isolate.WhenCalled(() => activationProperties.Item).WillReturn(item);
            Isolate.WhenCalled(() => item.Name).WillReturn("test.docx");
            // Fire the workflow completed event
            Isolate.Invoke.Event(() => approvalWorkflow.Completed += null, new object[] { this, EventArgs.Empty });

            Isolate.Verify.WasCalledWithExactArguments(() => item.CopyTo("http://xdev03.trading.ad.int.corp.local/Policies/test.docx"));

When executed it throws the following exception:

System.NotSupportedException: Cannot dynamically create an instance of System.Void.

at Total.SharePoint.Approval.Workflow.Test.ApprovalWorkflowFixture.PublishToExternalDocumentLibrary_Calls_CopyTo_Correctly() in ApprovalWorkflowFixture.cs: line 0 

I can work around this issue by replacing the line:

Isolate.WhenCalled(() => activationProperties.Item).WillReturn(item);


Isolate.NonPublic.WhenCalled(activationProperties, "get_Item").WillReturn(item);

InfoPath forms with workflow: ‘The form has been closed’ or Exception occurred during request processing. (User: {Domain}\{UserName}, Form Name: , IP: , Request: http://localhost/_layouts/CstWrkflIP.aspx?List={ID}, Form ID: , Type: InfoPathLocalizedException, Exception Message: The specified form cannot be found.)

Okay so today’s error message, totally my fault: was

Exception occurred during request processing. (User: DOMAIN\xx, Form Name: , IP: , Request: http://localhost/_layouts/CstWrkflIP.aspx?List={ID}, Form ID: , Type: InfoPathLocalizedException, Exception Message: The specified form cannot be found.)

Make sure that:

  • Your feature file has the RegisterFroms property correctly pointing to a folder in your solution package that contains your infopath forms

    WindowClipping (23)
    In my example all my info paths forms are contained in a sub directory called ‘Forms’ relative to feature file:
    WindowClipping (24)

  • Once the feature has been installed using stsadm –o install feature check that the forms have been placed in the InfoPath template library.

    Central Administration –> Application Management –> Manage Form Templates:

    WindowClipping (25)

As always, your mileage my vary. If this doesn’t help you could try some of the tips on Lucy’s blog: http://blogs.tamtam.nl/lucy/2007/06/08/WorkflowErrors.aspx

Toolbox –> "Choose items" crashes Visual Studio

If you ever encounter a crash when choosing the items to display in Visual Studios toolbox, then try this solution:


  • Start Visual Studio in safe mode using:  Start->Run->devenv /safemode
  • In the Toolbox “Choose items”, accept any error message the appear
  • Restart Visual Studio as per normal and the problem should be fixed.

Cannot change the lookup list of the lookup field.

Ever get this error message

SPException “Cannot change the lookup list of the lookup field.”

Once a lookup field (SPFieldLookup) has had it’s LookupList and LookupWebId set you can’t change them.

There is a good reason for this if your lookup field is used in multiple lists or already has data entered, you would effectively break the referential integrity of the data. So what I’m showing here as a work-around to this error message should only be used if you are *sure* no lists reference the lookup column or no lists have any data using this column

Okay with the health warning out of the way the work-around is simply to update the Schema property to overwrite the intervalues for List & WebId

I created a handy extension method for dealing with the string manipulation:


SPFieldLookup field = (SPFieldLookup)site.RootWeb.Fields[MyId];
field.UpdateLookupReferences(newWeb, newList);


public static class SPFieldLookupExtensions
    public static void UpdateLookupReferences(this SPFieldLookup lookupField, SPWeb web, SPList list)
        if (string.IsNullOrEmpty(lookupField.LookupList))
            lookupField.LookupWebId = web.ID;
            lookupField.LookupList = list.ID.ToString();
            lookupField.SchemaXml =
                    .ReplaceXmlAttributeValue("List", list.ID.ToString())
                    .ReplaceXmlAttributeValue("WebId", web.ID.ToString());


public static string ReplaceXmlAttributeValue(this string xml, string attributeName, string value)
    if (string.IsNullOrEmpty(xml))
        throw new ArgumentNullException("xml");

    if (string.IsNullOrEmpty(value))
        throw new ArgumentNullException("value");

    int indexOfAttributeName = xml.IndexOf(attributeName, StringComparison.CurrentCultureIgnoreCase);
    if (indexOfAttributeName == -1)
        throw new ArgumentOutOfRangeException("attributeName", string.Format("Attribute {0} not found in source xml", attributeName));

    int indexOfAttibuteValueBegin = xml.IndexOf('"', indexOfAttributeName);
    int indexOfAttributeValueEnd = xml.IndexOf('"', indexOfAttibuteValueBegin + 1);

    return xml.Substring(0, indexOfAttibuteValueBegin + 1) + value + xml.Substring(indexOfAttributeValueEnd);

If your workflow uses validation rules it might be:

1) A problem with your validation rules, restart Visual Studio re-compile are any errors picked up?


2) Missing the .net 3.5 workflow targets in your project file see: http://blog.hhebnes.no/post/WSPBuilder-Workflow-Failed-On-Start.aspx

An error occured while validating or updating the directory service connection. No update was performed.

I got this error whilst trying to get User Profiles to work. Things to check:


  1. Domain name is correct
  2. If using custom sources, try creating a new custom source and deleting the old one

SharePoint custom workflow activity. “Failed to load toolbox item. It will be removed from toolbox.”

I was getting this error message in Visual Studio 2008 when adding a custom activity to an existing workflow.



This worked for me, your mileage, may and probably will vary.

It was necessary for me to un-gac the workflow project, then the custom activities could be added to the design surface as expected.

Event log error message

Safe mode did not start successfully. Could not load file or assembly ‘MyCompany, Version=, Culture=neutral, PublicKeyToken=XXXXXXXX’ or one of its dependencies. The system cannot find the file specified.


In my case the error message from the event log was spot on. I had accidentally removed a MyCompany assembly from the GAC.


Other errors can also cause the same problem, whilst debugging this issue I came across another blog post that might be of interest: http://www.dotnetmafia.com/blogs/dotnettipoftheday/archive/2008/09/24/safe-mode-did-not-start-successfully-request-failed.aspx

Programmatically determine is a feature is activated or even installed

Okay so ever needed to see if a particular web or site feature is activated? Well if it’s activated it will be in the SPWeb.Features SPFeatureCollection or SPSite.Features. If it’s not activated it won’t be. Simple.

To check if a feature is installed examine the feature definitions collection on the SPFarm object, below are a couple of little extension methods that demonstrate this concept.

/// <summary>
/// Defines extensions made to the <see cref="SPWeb"/> class
/// </summary>
public static class SPWebExtensions
    public static bool IsFeatureActivated(this SPWeb web, Guid featureId)
        return web.Features[featureId] != null;

    public static bool IsFeatureInstalled(this SPWeb web, Guid featureId)
        SPFeatureDefinition featureDefinition = SPFarm.Local.FeatureDefinitions[featureId];
        if (featureDefinition == null)
            return false;

        if (featureDefinition.Scope != SPFeatureScope.Web)
            throw new GeneralApplicationException(
                string.Format("Feature with the ID {0} was installed but is not scoped at the web level.", featureId));

        return true;

The imported project “C:\Program Files\MSBuild\Microsoft.Office.InfoPath.targets” was not found

If you get this error message, which I did this morning opening up someone else’s SharePoint solution, make sure you have InfoPath installed.

Microsoft Visual Studio


Once I installed the InfoPath client application  with .Net Programmability Support, see below, the targets file was installed to the MSBuild directory.

Microsoft Office Enterprise 2007
