FormsAuthentication.SignOut() results in System.NullReferenceException

  

Hi. I am getting a "System.NullReferenceException" when I call

Custom sequence activity deriving from System.Workflow.Activities.SequenceActivity

  
Hi, I try to create custom sequence activity. I found some sample (http://social.msdn.microsoft.com/Forums/en-US/wfprerelease/thread/f54e8eb2-29d9-46f6-ad96-766fe6fad333/). But this custom activity looks ugly (to separate nested activity using ellipses instead of arrows). My question is - how to create custom sequence activity, which will look like sequence activity. I also found this sample - <ContentPresenter x:Uid="ContentPresenter_1" Content="{Binding}" Style="{x:Static sacdt:DesignerStylesDictionary.SequenceStyle}"/> When I used this ContentPresenter my custom activity looks like System.Workflow.Activities.SequenceActivity, but I couldn't put on it another activity. I also created class, which derives from System.Workflow.Activities.SequenceActivity, but I couldn't see it in toolbox. My question is - how to create class, which derives from System.Workflow.Activities.SequenceActivity and is visible in toolbox or how to use ContentPresenter for sequence activity, which allows put on itself another activity.

List does not exist -- AutoStart Workflow: System.NullReferenceException:

  

I have been in a discussion on the MSDN forums concerning a site with which I am having considerable issues.  (http://social.msdn.microsoft.com/Forums/en-US/sharepointdevelopment/thread/0feaf4c7-77cd-46c6-b3cd-4d18c69b18c3)    There is one issue that keeps cropping on one of the pages on that site.  The page is a customization of the EditForm.aspx which is being used to edit folders. We call it EditFolderForm.  Like the EditForm it uses a DataFormWebPart.  It also has a SharePoint:SaveButton  and a SharePoint:GoBackButton.  The Listid on the page has been confirmed to be the correct ListID.  Clicking the SaveButton causes the following two errors:

List does not exist  The page you selected contains a list that does not exist.

and then

AutoStart Workflow: System.NullReferenceException: Object reference not set to an instance of an object.

I have found references that mentioned getting these messages for custom made workflows that are built on Designer.  However the workflow being called is a built in SharePoint Workflow so that none of the suggested fixes will work.  (Also it seems that the workflows that cause the issue seem to be sending

System.NullReferenceException

  

 SET UP

I have an obout.grid (me.gridsettings1) on a user control that loaded onto a aspx page.

Within a method on the user control, I run thru selected records like this..to get a data item , thats is an integer.

 

    Private Function getSelectedRowUserGroupID() As Integer
        Dim s As Integer
        If Me.gridSettings1.SelectedRecords.Count > 0 Then 'HERE
            For Each rec As Hashtable In Me.gridSettings1.SelectedRecords
                s = CInt(rec("UserGroupID").ToString)
            Next
            Me.gridSettings1.SelectedRecords.Clear()
        End If
        Return s
    End Function


 It works fine for about 1 or 2 times then asp.net throws up this error : System.NullReferenceException: Object reference not set to an instance of an object.

for line marked "HERE

So it telling me it cant find the control on on the ascx/aspx page, but its there fine ?

Any ideas...


.NET Runtime 2.0 Error Reporting event id 5000 system.nullreferenceexception

  

I only found http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=389835&SiteID=17 regarding this error message and it was of no help to me.
