• Nirupam Pratap Reddy StateMachine / Tracking Service / Not Logging Final State Change

  Hi, Using WWF Beta 2 (Jan CTP). In reviewing tracking history for a statemachine workflow, the final statechange doesn't seem to be logged or it's not being returned via SqlTrackingWorkflowInstance.UserEvents with UserDataKey of "StateActivity.StateChange". I'm using the default tracking profile and have tested against a few different workflows. The workflow status itself is completed. One note is that the final workflow does not have ...Show All

• PatGO Modelling a collection and item relationship

  I'm looking to implement a state machine for a job system. The lowest level item is a Job, but I would also like to have the ability to group jobs together i.e a batch of Jobs.  Both a batch and a job would have states like Open, Assigned, Completed, Closed etc. So you could have a Open batch with half of the Jobs completed one Closed and one assigned. Valid states for a batch would be dependent on all the Jobs in the batch i.e only closed ...Show All

• MKSubb State Machine Design Question

Also, if a review by a particular user is not performed within a specific time I would like to take some alternate action. My question is as follows: How do I design a State such that it stays in the state until N users perform some discrete action ( like fir ...Show All

• Dave Fackler StateMachine: Having state without IEventActivity as first child?

  Hey guys, I have the following problem (including not so pretty workaround): In a state machine I want to be able to transition state but immediately continue working in that other state. In my particular case one state can be reached from multiple other states (of course, that's the purpose of a state machine) but the first activity in there is not an IEventActivity, i.e. I'm not receiving an event but continue with a couple ExternalMetho ...Show All

• Jon Jung Scheduling workflow

  I have a workflow application (my first) that has several sequential workflows defined that are triggered based on incoming messages from a network socket. What I'm not sure on is how to marshal the incoming requests into the workflow, I could have up to 50/sec inbound requests that each need to be processed via a workflow. At the moment, for each request I do a CreateWorkflow().Start, and while that works for OK for the moment, I'm not s ...Show All

• starkami More simplistic conditions and branches

  IfElse is fine, but we would like a very simple YesNo container that branches based on a property value of the preceding activity. Any suggestions on how this might be implemented Is it possible to determine the task immediately before your task What steps are required to present a drop-down list of the available boolean properties on the preceding task We could use reflection and build our own custom UITypeEditor, but I know the EventSink does ...Show All

• AVNIP ASP.Net & ManulScheduler Nightmares...

  Well the isues go on... The details: 1. When a delay activity is arrived at in a workflow and that instance is persisted. 2. When a new instance is created, the previous instance is loaded, but doesn't go any where, and when the delay is reached the item is persisted. Why doesn't it carry on I did some digging and found out that you needed to call the RunWorkflow(Guid) method on the Manual Scheduler, so I added the following code to my Workflow ...Show All
