  • Windows Workflow Foundation 4 (WF4) ReHosting

    - by Russ Clark
    I've been looking at the possibility of ReHosting a WF4 Workflow to be used to debug running Workflows. All the posts and samples I've seen regarding WF4 Rehosting are using a WPF application to initially Host the Workflow, and then use the WorkflowDesigner in ReHosting it. Is there any way to Rehost a Workflow that was hosted in a non WPF application, like ASP.Net MVC?

  • Loading persisted workflow after workflowdefinition has changed in WF4

    - by Flores
    How to solve this problem (in WF4): I create a workflow in xaml and start several instances of it, I have a persistancestore and all workflows persist on a bookmark half way their workflow. Now I stop the application If I restart te application everything is resumed, en nicely completes. But what if I want to change the workflow definition after the running instances persist? the only way to load the running workflows (that I was able to find) is the following way: WorkflowApplication wfapp = new WorkflowApplication(new WorkflowDefinition()); wfapp.InstanceStore = new SqlWorkflowInstanceStore(connStr); wfapp.Load(wfGuid); So you need the workflow definition, if it has changed during the persistance, things go horribly wrong. What is the best way to solve this?

  • High Throughput and Windows Workflow Foundation

    - by SometimesUseful
    Can WWF handle high throughput scenarios where several dozen records are 'actively' being processed in parallel at any one time? We want to build a workflow process which handles a few thousand records per hour. Each record takes up to a minute to process, because it makes external web service calls. We are testing Windows Workflow Foundation to do this. But our demo programs show processing of each record appear to be running in sequence not in parallel, when we use parallel activities to process several records at once within one workflow instance. Should we use multiple workflow instances or parallel activities? Are there any known patterns for high performance WWF processing?

  • Workflow of sharing code for small teams

    - by Mihalis Bagos
    Problem is, we have developed a small CMS, that is different per implementation (currently). Of course development of this is never complete. Sometimes, we are working on more than one project that implements it (by copying-pasting the code files of the CMS to each project), and we add a new feature that we want to share on other projects as well (these can be small ones too, ie a custom ajax JSON controller - we use MVC) What we want to do is quickly and uniformly share the code with all other projects, via a version control system (or something similar), and generally organize the workflow as we know this isn't a very good workflow that we have. What would you suggest? Also, at the momment, the software we use is Visual Studio 2010, so we are strongly considering TFS, but even if we get it we still don't know the ideal workflow, or even if TFS supports what we want to do. Edit: Also note, we have specific implementations that have modifications over the CMS base that we want to KEEP only in the project area. (ie: a specific feature that we DONT want to share with the base CMS code)

  • Team Leaders & Authors - Manage and Report Workflow using "Print an Outline" in UPK

    - by [email protected]
    Did you know you can "print an outline?" You can print any outline or portion of an outline. Why might you want to "print an outline" in UPK... Have you ever wondered how many topics you have recorded, how many of your topics are ready for review, or even better, how many topics are complete! Do you need to report your project status to management? Maybe you just like to have a copy of your outline to refer to during development. Included in this output is the outline structure as well as the layout defined in the Details View of the Outline Editor. To print an outline, you must open either a module or section in the Outline Editor. A set of default data columns is automatically included in the output; however, you can configure which columns you want to appear in the report by switching to the Details view and customizing the columns. (To learn more about customizing your columns refer to the Add and Remove Columns section of the Content Development.pdf guide) To print an outline from the Outline Editor: 1. Open a module or section document in the Outline Editor. 2. Expand the documents to display the details that you want included in the report. 3. On the File menu, choose Print and use the toolbar icons to print, view, or save the report to a file. Personally, I opt to save my outline in Microsoft Excel. Using the delivered features of Microsoft Excel you can add columns of information, such as development notes, to your outline or you can graph and chart your Project status. As mentioned above you can configure what columns you want to appear in the outline. When utilizing the Print an Outline feature in conjunction with the Managing Workflow features of the UPK Multi-user instance you as a Team Lead or Author can better report project status. Read more about Managing Workflow below. Managing Workflow: The Properties toolpane contains special properties that allow authors to track document status or State as well as assign Document Ownership. Assign Content State The State property is an editable property for communicating the status of a document. This is particularly helpful when collaborating with other authors in a development team. Authors can assign a state to documents from the master list defined by the administrator. The default list of States includes (blank), Not Started, Draft, In Review, and Final. Administrators can customize the list by adding, deleting or renaming the values. To assign a State value to a document: 1. Make sure you are working online. 2. Display the Properties toolpane. 3. Select the document(s) to which you want to assign a state. Note: You can select multiple documents using the standard Windows selection keys (CTRL+click and SHIFT+click). 4. In the Workflow category, click in the State cell. 5. Select a value from the list. Assign Document Ownership In many enterprises, multiple authors often work together developing content in a team environment. Team leaders typically handle large projects by assigning specific development responsibilities to authors. The Owner property allows team leaders and authors to assign documents to themselves and other authors to track who is responsible for a specific document. You view and change document assignments for a document using the Owner property in the Properties toolpane. To assign a document owner: 1. Make sure you are working online. 2. On the View menu, choose Properties. 3. Select the document(s) to which you want to assign document responsibility. Note: You can select multiple documents using the standard Windows selection keys (CTRL+click and SHIFT+click). 4. In the Workflow category, click in the Owner cell. 5. Select a name from the list. Is anyone out there already using this feature? Share your ideas with the group. Those of you new to this feature, give it a test drive and let us know what you think. - Kathryn Lustenberger, Oracle UPK & Tutor Outbound Product Management

  • Persistent workflow with durable delay activity hosted in ASP.NET

    - by Petr Felzmann
    The situation: a workflow hosted in ASP.NET application using WorkflowServiceHost and contains durable delay. The workflow is currently inside the delay activity and was persisted into database. Then the application pool, under which the ASP.NET application is running, goes to be recycled (e.g. by web.config change) and there are no more http requests to the ASP.NET application. And now is the time when delay activity should finish and next activity in the workflow should be executed. Does it mean the next activity will not be executed until any request to the ASP.NET application because the app pool was recycled?

  • Windows Workflow Foundation 4 (WF4) Error Handling

    - by Russ Clark
    What is the best way to get error messages from a WF4 workflow back to a hosting ASP.NET MVC application? I need the workflow to not terminate, but continue to be active, and then pass a message back to the hosting app regarding the error, so the user can take an alternative action, but I'm not sure how to do that.

  • How to copy items using Nintex Workflow

    - by ybbest
    Nintex does not offer copying items from one SharePoint library to another out of box. However, it is not hard to implement one yourself. You can use the copy.asmx web services to achieve this. Here are the steps below and you can download the source here 1. Create a UDA with the following parameters: 2. Call the copy.asmx service to copy the item from SouceItemUrl to DestinationItemUrl 3. If your destination document library has versioning and check-in/out turned on , you can use list.asmx to check in your file as below: 4. You need to create constant of Credential type named SP_WORKFLOW_WS as below 5. Here is how it looks like in the Workflow designer. 6. To call this UDA, you can perform the following in your workflow

  • Examples of continuous integration workflow using git

    - by Andrew Barinov
    Can anyone provide a rough outline of their git workflow that complies with continuous integration. E.g. How do you branch? Do you fast forward commits to the master branch? I am primarily working with Rails as well as client and server side Javascript. If anyone can recommend a solid CI technology that's compatible with those, that'd be great. I've looked into Jenkins but would like to check out other good alternatives. To put some context into this, I am planning on transitioning from working as a single developer into working as part of the team. I'd like to start standardizing my own personal workflow so that I can onboard new devs quickly.

  • Workflow Foundation (WF) -- Why does Visual Studio's designer not use my custom ActivityDesignerThem

    - by stakx
    Problem: I am trying to customize a custom Workflow Foundation activity (called CustomActivity) so that it will display with a specific background color. What I've got so far: First, I'm defining a custom ActivityDesignerTheme as follows: public class CustomActivityTheme : ActivityDesignerTheme { public CustomActivityTheme(WorkflowTheme theme) : base(theme) { this.BackColorStart = Color.FromArgb(0xff, 0xf4, 0xf4, 0xf4); this.BackColorEnd = Color.FromArgb(0xff, 0xc0, 0xc0, 0xc0); this.BackgroundStyle = LinearGradientMode.Horizontal; } } Then, I am applying this theme to a custom ActivityDesigner (apparently the theme must be applied to a designer, and not to an activity): [ActivityDesignerTheme(typeof(CustomActivityTheme))] public class CustomActivityDesigner : SequentialActivityDesigner { ... } Ultimately, I am applying the custom designer to my custom Activity: [Designer(typeof(CustomActivityDesigner))] public partial class CustomActivity : SequenceActivity { ... } Now, according to some code examples that I've seen, this should do the trick. However, when I include an instance of my CustomActivity in a workflow, my custom theme is not applied and it is displayed in the Visual Studio Designer as any standard activity would (white background etc.). I tried re-compiling and even re-starting Visual Studio a couple of times, just to make sure the used assembly is up-to-date, but to no avail. My question: What am I missing? Why does Visual Studio's Workflow Designer not respect the CustomActivityTheme when it displays a CustomActivity?

  • How to implement reject in parallel approval workflow?

    - by Dmitry Martynov
    I develop a SharePoint workflow with a Replicator activity to replicate a custom activity for every approver. The custom activity implements an approval branch for a particular user. It has classic form with CreateTask, While, OnTaskChanged and CompleteTask activities. I setup UntilCondition on the replicator to cancel execution after one approver chooses to reject the approval and then workflow finishes. The problem happens with other uncompleted tasks which "hang" in their current state. User does not see this state when open the task. I put UpdateAllTasks after the replacator to set the task status to Cancelled. But since there is no event activities between CompleteTask (for the rejected task) and UpdateAllTasks, the UpdateAllTask activity set Cancelled for the rejected task also. The question, what can I do to flush the pending change made by CompleteTask before UpdateAllTasks? Or perhaps, there is another way to implement such workflow. I was thinking about the way to implement Cancel handler for the custom activity with UpdateTask. But I do not know how to implement it and tell to the cancel handler that it executes in the case of the rejection.

  • Windows Workflow Foundation 4.0 and WCF web service faults (soap fault)

    - by Lygpt
    In my Workflow Foundation 4.0 RC app I have a 'Receive' and 'SendReplyToReceive' WCF messaging pair that work fine with a simple request/response operation, but I'm having trouble attempting to perform validation on the request and reply with a fault. In WCF I am able to create a throw custom fault contracts (which in turn sent out SOAP faults) but I just can't see how to achieve this with the built-in workflow messaging activities. I can only seem to response with a data transfer object (I'm not even able to respond with a choice of object). Any ideas? (Can you save my day yet again Maurice!?) Thanks!

  • Windows Workflow Foundation 4 (WF4) Delay

    - by Russ Clark
    I'm working with the the Release Candidate of Visual Studio 2010 using Wf4 to write a new workflow for approving resource requests. In my workflow, I would like for a request to expire after a few days if no approval has been made for the request. We did this in WF 3.5 (Visual Studio 2008) by adding a Delay timer into an EventDrivenActivity parallel to the EventDrivenActivity that was awaiting an approver to come and approve the request. If the Delay expired before an approval was made, the EventDrivenActivity would terminate the request. Does anyone know if there is a similar mechanism for doing this in WF4?

  • Reference a internal class from a Windows Workflow Activity

    - by Ben Hughes
    I'm creating a custom Workflow activity for use within TFS2010. In the same assembly I have a XAML activity and a C# code activity. The XAML activity references the code activity. When the assembly is deployed to our clients, I only want them to be able to use the Workflow activity. The code activity is of little use by itself and would no doubt confuse them. I thought the logical way to do this would be to set the code activity class to internal: the XAML is in the same assembly and should be able to access it. However, when I do that I get an error in the XAML saying that the assembly can't be found. Is there a way to make activities internal/hidden?

  • Windows Workflow Foundation 4 (WF4) Bookmark

    - by Russ Clark
    I'm working with Visual Studio 2010 and have a workflow where I'm trying to resume a bookmark. The bookmark appears to be getting set just fine, but when I try to run the code below to resume it, I get an entry in the InstancesTable in the persistence database with the SurrogateLockOwnerID field set to an integer, usually this field is null, and I can no longer do anything with the workflow. I think this is indicating that I have some kind of blocking lock going on, but I can't find any references anywhere to the SurrogateLockOwnerID. Does anyone know what is causing this, and how to fix it? WorkflowApplication workflowApp = new WorkflowApplication(new WebCARSWorkflow()); workflowApp.Extensions.Add(new SqlTrackingParticipant(ConnString)); InstanceStore instanceStore = new SqlWorkflowInstanceStore(ConnString); workflowApp.InstanceStore = instanceStore; workflowApp.Load(WorkflowInstanceId); workflowApp.PersistableIdle = (waie) => PersistableIdleAction.Unload; Approver actualApprover = new Approver(ProcessingStatus.Awaiting, my_RDA_Role, "RDAGetPlayersFromExternalRoleURI", 14); actualApprover.ActionDate = DateTime.Now; Player actualPlayer = (Player)GetPlayer(login); actualApprover.ActualPlayer = actualPlayer; actualApprover.ApproverAction = action; workflowApp.ResumeBookmark("ErrorOccurredBookmark", actualApprover);

  • ASP.NET MVC 4 async child action

    - by ShadowChaser
    I have an ASP.NET MVC 4 application targeting .NET 4.5. One of our child actions makes a call out to a web service using HttpClient. Since we're blocking on IO waiting for the HttpClient response, it makes a great deal of sense to convert the code to the async/await pattern. However, when MVC 4 attempts to execute the child action, we get the following error message: HttpServerUtility.Execute blocked while waiting for an asynchronous operation to complete. At first glance, it appears as though MVC 4 does not support async/await within a child action. The only remaining option is to run using synchronous code and force a "Wait" on the async task. As we all know, touching .Result or .Wait() on an async task in an ASP.NET context will cause an immediate deadlock. My async logic is wrapped in a class library, so I can't use the "await blah.ConfigureAwait(false)" trick. Remember, tagging "async" on the child action and using await causes an error, and that prevents me from configuring the await. I'm painted into a corner at this point. Is there any way to consume async methods in an MVC 4 child action? Seems like a flat out bug with no workarounds.

  • Is Microsoft Workflow Foundation really used ?

    - by ereOn
    Today, I had a training on "Microsoft Workflow Foundation". While I think the idea is neat, I still see it as a Proof Of Concept and not as a real-life solution. Building an entire application without having to type a single line of code (or only a few of them) seems just wrong. Have you ever used this technology and if so, can it really fit to big company projects ? What drawbacks/advantages have you got using it ?
