CorrelationInitializer question

Hi, I'm new to wwf, and I have the following question,

In all the available application samples I browsed the CorrelationInitializer is always attributed to a method, and not to an event. Is there a reason for this

The usual is something like:

   [ExternalDataExchange]
    [CorrelationParameter("nextStage")]
    public interface ISMConnector
    {
        [CorrelationAlias("nextStage", "e.Command")]
        event EventHandler<RegEventArgs> OwnerInfoSubmitted;

        [CorrelationInitializer()]
        void SMSnapshot( string nextStage);
    }

I had originally thought of doing something more like:


    [CorrelationParameter("WorkflowInstanceId")]
    [ExternalDataExchange]
    public interface ICaseManagementLocalService
    {
        [CorrelationInitializer]
        [CorrelationAlias("WorkflowInstanceId", "e.Case.WorkflowInstanceId")]
        event EventHandler<CaseEventArgs> CaseCreated;

        [CorrelationAlias("WorkflowInstanceId", "e.Case.WorkflowInstanceId")]
        event EventHandler<CaseEventArgs> CaseUpdated;
    }

Is there a problem with defining the CorrelationInitializer as an event (I'm having problems with this approach).

thanks,

I've made an event the correlationinitializer - this is definately legal. You don't need the CorrelationAlias attribute on the CaseCreated event. I am not sure about the property of a property syntax howerver (it may work - but I've never done it).

Are you handling the WorkflowRuntime.WorkflowTerminated event My guess based on that exception is that your workflow is terminated before you are expecting it to.

Yeah, I'm getting EventDeliveryFailedException: Event "CaseUpdated"....System.InvalidOperationException: Workflow with id "d9c3f57b-2<BR>834-47a7-8403-649cc7bfd175" not found in state persistence store.

This happens when I execute this piece of code to test the wf:

CaseData cd = GetDummyCaseData(); CaseManager manager = new CaseManager(); //raises CaseCreated event string instanceid = manager.OpenNewCase(caseData);caseData.WorkflowInstanceId = instanceid; caseData.CaseStatus = "Assigned"; caseData.AssignedTo = "technician"; //raises CaseUpdated event manager.UpdateCase(caseData, "dispatcher");But I'm not paying much attention to the exception because I know things are already inconsistent before I get the exception.The state machine defined looks like this, and the initial state is something like this.

When I raise the CaseCreated event, I know the handleExternalEventActivity1_Invoked handler gets invoked, because it writes in the EventLog, but the second activity (PersistCaseData, the code activity) never gets executed.

Persistence service is enabled, if I look at the persistence database, each time I run the test code, a new row appears in the WorkflowInstance table. So I guess It's just unloading on idle somewhere, but I don't get why, and why it just doesn't run the code activity and continue to the next state.

Any hint will be appreciated,

Yes to state machine - dont' remember if I was using persistence.

Are you getting exceptions

that was it!

THANKS!!

Jon,

In your case, were you working with a state machine workflow was persistence enabled

thanks,
