Error: EventDeliveryFailedException ?

Error: EventDeliveryFailedException ?

• Craig Mellon

  This doesn't fix the problem, but I switched my workflow over to a Sequential Workflow like they use in the ExpenseReport application. The workflow works fine and without the need of a correlation token.

  I used the SQL traking sample and everything is synchronized and flows as expected. I went ahead and changed values and persisted the object independant from the workflow and everything pans out.

  So, since I didn't change my events, event args, or anything but the workflow. This leads me to believe that the difference is between sequential and state workflow local communications.

  I know this is not an answer to the problem, but hopefully it will get us closer to a solution.

  Take care,

  John

  Having looked up correlation tokens I don't think they would be required This is a state machine, and there are no parallel activities. Unless one counts the various event-driven activities which can happen at different points.

  Can you post the entire stack trace Are you using correlation Is the correlation token properly initialized

  Thanks,

  I'm having the same problem in a sequential workflow that was recently updated to a new version. All versions are available in the GAC. The error is raised when trying to raise an external event on the workflow from an instance of the previous version. Can anyone provide some help As it is now I am stuck using the original workflow version and can't make any changes because changing anything breaks everything.

  Thanks - that helps confirm what I suspected: it's a bug with State machine workflows.. or possibly we are missing some action that is required for State machines when used under ASP.NET in some set of circumstances - perhaps when Persistence is used..

  I took the MS ASP example workflow ( a sequential workflow) and added an event handler and it worked fine, which strongly confirms what you suggest: State machine is broken

  I think I will post it as a bug unless MS can explain what's missing

  I am beginning to suspect my translation of C# into VB - perhaps the event handler in a C# service example..
  
    public event EventHandler<MyEventArgs> SomeEvent;
  
  Which from looking at VB examples (the MSDN helpdesk example), should translate to ..
  
    Public Event SomeEvent(ByVal sender As Object, ByVal e As MyEventArgs) Implements IMyInterface.SomeEvent
  
  
  I am sure this isn't right, as surely it should be

    Public Event SomeEvent As EventHandler(Of MyEventArgs) Implements IMyInterface.SomeEvent

  Thanks for the suggestion..

  I couldn't find an EnqueOnIdle flag as part of ExternalDataEventArgs (I am using beta2 - is it present on 2.2 ).

  There is a WaitForIdle flag but setting this resulted in the workflow blocking the ASP.NET thread to wait while it raised the event - except of course it would wait forever as it was ManualWorkflowScheduler

  Did adding the correlation tokens fix the problem

  I am having the same problem and I was wondering why the ExpenseReport sample from Microsoft works. I don't see any correlation tokens in thier code.

  Any information that helps would be greatly appreciated.

  Thanks,

  Thanks for the help - nope - I already checked that my arguments were serializable.
  
  I am currently looking at an excellent PluralSight blog with an example that shows a workflow across ASP.NET, WinForms and Console.
  
  I just don't seem to be able to get the raising events to work in my application.

  Having looked, the inner exception is:

  System.InvalidOperationException: Event Queue operation failed with MessageQueueErrorCode QueueNotFound for queue 'Message Properties
  Interface Type:WorkflowLibrary.ICreditControl
  Method Name:CalledCustomerPromisedPayment
  CorrelationValues:

  Howard -

  State machine does have a minor difference. You will have to set the EnqueueOnIdle flag to true before sending messages to avoid problems with delivering messages to sinks not in the current state of the state machine.

  Please see an earlier post:http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=260293&SiteID=1

  If that still doesn't help, do let me know.

  Thanks,

  Just a guess, but check your InnerException and see if it says something about EventArgs not serializable.

  If so, then you are experiencing a similar problem to what alot of us here have already encountered and you will need to change your code to pass null as the sender parameter when raising the event.

  From my perspective, this is a bug in the WWF that needs to be addressed.

  If this is not the problem that you are having then ignore my rambling ;-), it's just that the only time I had this problem with raising an event 'into' the workflow that's what it turned out to be.

  Here is the full trace. There is nothing about 'correlation token properties' - at least nothing I have implemented (don't know what they are).
