You get to choose what you want to do, either keep running existing instances with their original workflow definition or upgrade them to the latest workflow definition. If you find a bug in your workflow definition the update scenario is probably what you are looking for. In this blog post I am going to explain how to do an upgrade of an existing workflow instance. Make some changes to the workflow definition. The Problem Solver - Wednesday, October 10, 2012 Spring 3.0 and the Enterprise Training Processes and best practices are discussed and illustrated through both discussions and group activities. Students who attend Spring 3.0 and the Enterprise will leave the course armed with the required skills to design and implement Spring applications that effectively and transparently use various enterprise systems, tools, and technologies. This course provides coverage of the concepts and practices for interacting between Spring and relational databases, security components, distributed resources, web services, messaging, EJB3, and other components.

The Problem Solver - Wednesday, October 10, 2012 Xanpan: refining the process In my last blog entry I discussed a Xanpan board layout which allows for planned and unplanned work to co-exist in one workflow. In this case the workflow and work in progress. My rules are quite straight forward for Xanpan boards: Stage 1: Model the current workflow on the board: avoid changing it too much to “how it should be” but you will probably need to modify the workflow a little in order to be able to model it. Make sure you talk through various scenarios for work to make sure you have a workflow that will, well, work. Allan Kelly's Blog - Monday, December 12, 2011 | -
| The Best from DevelopMentor | MORE | - Workflow Receive activity and message correlation
With WF4 it is quite easy to use data that is part of the request message, for example an order identifier, to route multiple WCF messages to the same workflow. It is also possible to have multiple messages that can start a new workflow. In this blog post I am going to show both these concepts in a single workflow. This workflow is going to be able to receive three different messages, AddItem, AddExpensiveItem and Submit. Either AddItem or AddExpensiveItem can start a new workflow while Submit can only be done with an existing workflow. ReferenceID0. The Problem Solver - Wednesday, April 28, 2010 - Flowcharts in Workflow 4 and the Switch activity
Flowcharts are a nice addition to Windows Workflow Foundation 4. They allow for a lot of pretty complex behavior that is hard to do in a sequential workflow. In WF 3 we used to model these complex behaviors as state machine workflows. Enter the flowchart in Windows Workflow Foundation 4 One of the good things is that a flowchart is not another workflow type. No it is just another activity to drop in a workflow. So you are free to combine sequential work with a flowchart in one workflow. Tags: NET Workflow WF4 VS2010 So far so good. The Problem Solver - Tuesday, October 27, 2009 - Bookmarked Activities in WF4
Beta 2 Windows Workflow Foundation 4 introduces the concept of bookmarks to temporarily pause activities. bookmark is basically a named pause point in an activity. The result is that the workflow runtime doesn’t consider an activity to be finished until all its bookmarks are either resumed or removed. The other option is BookmarkOptions.NonBlocking which means that the activity is finished even if the bookmark was never resumed. Running the workflow and resuming a bookmark is easy when using a WorkflowApplication as seen below. Enjoy! The Problem Solver - Tuesday, January 26, 2010 - Rehosting the Workflow Designer in WF4
Beta 2 With Windows Workflow Foundation 3 it was possible to rehost the workflow designer in your own application. With Windows Workflow Foundation 4 live has become much better on the rehosting front In fact it is possible to create the fully functional and useful workflow editor below in about 200 lines of code. And loading or saving a workflow is easy to, all it takes is a Load() and Save() function pointing to a XAML file. One thing that is needed is to register the workflow activity designer metadata. Validating the workflow. Sweet. The Problem Solver - Wednesday, December 23, 2009 - Windows Workflow Foundation 4 and persistence
The persistence class out of the box is called SqlWorkflowInstanceStore and as the name suggests it saves workflow data in either SQL Server 2005 or 2008. We can attach it to either a WorkflowApplication or a WorkflowServiceHost and persist workflows when we want. This can be used to run only short lived workflows and doesn’t support persistence. var instanceStore = new SqlWorkflowInstanceStore(connStr); WorkflowApplication app = new WorkflowApplication(workflow); app.InstanceStore = instanceStore; app.Run(); Okay its a little more involved then that. Enjoy! The Problem Solver - Thursday, November 19, 2009 - Doing synchronous workflow execution using the WorkflowApplication
The WorkflowApplication is a great way to execute your workflows in process. For example executing a workflow and updating the state of the user interface is much simpler when the WorkflowApplication.Run() doesn’t finish until all work is done. Take this very simple workflow and its execution output. var workflow = new Sequence(). {. Activities = {. Executing the workflow synchronously. Making this workflow execute in a synchronous fashion is easy and requires only a very small change by setting the SynchronizationContext to a custom implementation. The Problem Solver - Friday, January 7, 2011 - What's New in Windows Workflow Foundation in.NET 4.5 (part 1)
There are lots of places where an activity has a child activity to execute, for example an If activity has a Then and an Else and executes either. These are of type Activity so by default you can add a single activity there. Want multiple child activities? Just add a Sequence and you can add as many child activities as you want. No longer Now we can just drag a new Activity and the designer will automatically wrap the existing activity in a Sequence. Search Searching through workflows is another big one. www.TheProblemSolver.nl The Problem Solver - Tuesday, September 27, 2011 %>
