Same here. I was too anxiously waiting for the article and putting my feedback in article 2 and after submitting see that artible. I have a question here

Will ECM Starter Kit for Microsoft Office SharePoint Server Beta II TR will work with Office SharePoint Server RTM?

What is the difference between the workflows in Visual Studio.Net 2005 and Worfklows in SharePoitn Designer 2007 technically and theoratically?

Regards,

JERRY

Hi Jerry, The ECM Starter Kit will work for the most part, although a few of the samples have been revised for RTM, and the RTM kit will include more:).

I'll cover this in the appendix later on;), but here are the key differences between the two:

SPD is geared toward the Web Designer/Business admin. It's easy to learn, and you don't have to write any code. You can put together a lot of workflows with just sequence of actions and conditions. The other cool thing about SPD is that you can deploy remotely (vs. VS, where you have to deploy on the server box)

However, there are a few limitations (deploys to a list at a time, no IP forms, only sequential workflows). So you will want to use VS if…

• You need to create a workflow that can be deployed to all lists in a site collection.

• You want to use InfoPath forms for your workflow

• You need more actions than the ones available by default in SPD

• You want to use state machine workflows

Adding CreateTask Activity to a SharePoint Workflow

Eilene,

Is there any documentation around explaining how, exactly, the correlation tokens are used?

For example, all the Sharepoint Task Activities (CreateTask, OnTaskChanged, etc) require a correlation token. The also require a GUID named "TaskId".

How are these related? Will the same task always use the same correlation token? Which one(s) do I set, and which are set for me? What exactly would happen if two activities had the same TaskId but different CorrelationTokens? Or vise-versa?

If there's a one-to-one mapping between CorrelationTokens and TaskIds, why not just use the TaskId as the token? I'm sure there's a reason, but it's never been explained.

I added a replicator activity to my workflow, inside the replicator, I added a CallExternalMethod Activity which updates a List Item.

There is no UntilCondition specified, which implies that the child activity should execute and the replicator should end. But this does not work. The replicator does execute the CallExternalMethod activity.

Any ideas???

I tried adding a sequence and the callexternalmethod inside the sequence with the proper OwnerActivityNAem(tht of the sequence). But still it does not execute the child activity.

Regarding correlation tokens...I've got a fairly simple workflow that I created. Basically all it does is:

1) Create a task

2) Waits for the task to complete (in a WhileActivity)

3) Once the task is complete, wait for the workflow item to update, using an OnWorkflowItemChanged activity inside a WhileActivity

4) Done

The CreateTask and OnTaskChanged activities are all using the same correlation token ("taskToken", not the default "workflowToken").

The OnWorkflowItemChanged activity is configured with the "workflowToken".

What I'm finding is that if at some point between creating the task and completing the task I go an edit the workflow item, the workflow gets into an odd state where it will not progress any further (i.e. if I then complete the task, it will be stuck there).

I assume this is just a case of using the wrong correlation tokens but I'm doing exactly what is suggested in this blog posting ("The Importance of Correlation Tokens").

Any ideas?

I create a workflow that implement these function:

-Parameter: SPFieldUserValueCollection to initialized replicator

1) Create a task

2) Waits for other task completed

3) Once the task is complete, wait for the other task completed, using an OnTaskChange activity inside a WhileActivity

4) Done

The CreateTask and OnTaskChanged activities are all using the same correlation token ("taskToken", not the default "workflowToken").

But I get problem.

My WF create tasks, but no jump to OnTaskChange Event. And at my CustomList, status of column workflow is "Completed"

Please help me!

Regarding correlation tokens...I've got a fairly simple workflow that I created. Basically all it does is:

1) Create a Replicator activity, Create a task for each user

2) Waits for the task to complete (in a WhileActivity)

3) Once the task is complete, wait for the other task completed, When all Task completed --> Done workflow.

But I get some problem:

- I set debug in OnTaskChange function, but program doesn't jump in. I can't catch event OnTaskChange. I set CreateTask, OnTaskChange activity with the same Token key TaskToken (different with main WorkFfow token).

-I set CreateTask and OntaskChange in SequenceActivity, and set this Composite activity in Replicator activity!

Please help me! I used to many effort but can't sole this problem!

I think the part of the article about correlation tokens is still largely vague. IE: "Sometimes developers use the workflow token as their task token; now all tasks map to the same thing, right? This isn’t quite correct. Make sure each group and object has its own token. For example, don’t use the overall workflow token for your tasks. Also, create a separate token for each distinct task"... Your telling people to do something differently but without the 'why' explained! I would love to see a lower level explanation.

I would also rather like to see an example on where we would use different workflow tokens within the same workflow.

Hello All,

I am having a problem with the sendemail activity. When the sendemail is in a serial sequence it works fine. But when it is in a parallel branch it does not work rather gives an error.

re: Developing Workflows in VS: Part 3 - Five Steps for Developing Your Workflow

Chandra — Fri, 18 Jul 2008 15:55:46 GMT

Hi,

Say i have 2 states in a state machine workflow.

On completing a task in state 1 creates two tasks one from state 1 and the other from state 2.

The problem that i am facing is thet i am able to complete the task from state 2 but not the new task that was created from task 1

I believe since we are moving to a different state which is state 2 we cant complete the task from the state 1

Any thoughts????

I have a OnWorkflowItemchanged activity in a State Machine Workflow where some code is executed when the this method is invoked followed by another activity for sending out the mail.

Although in this activity I am checking for a flag to prevent repeated execution as the items are saved and changed, the mail is going out 3 times eveytime a change is made to the document.

Please suggest....

re: Developing Workflows in VS: Part 3 - Five Steps for Developing Your Workflow

Daniel O'Brien — Tue, 16 Sep 2008 19:46:08 GMT

The fact that custom/composite activities don't have a reference to their parent workflow token really limits us as to what we are able to do.

If I create a custom activity that has a CreateTask (say, for example, to use in a replicator), that Task has really no knowledge of the Workflow it's running within. This causes some significant problems such as:

* No knowledge of what Task List the task is being created on. We know the ID...but not the list?!?!

* No reference to the Web, Site, Item, or Item List. How can our custom activity do any actions against a document or list entry if we can't find out what it is?!?!

Additionally, the SendEmailActivity, according to your chart above, needs the workflow token, which isn't available in a custom activity. Does this mean that sending email isn't available from there?

No offense, but this stuff is really cool when it works, but I can't help but think that the underlying architecture wasn't very well thought out...just my opinion...

If I'm missing something--some way of referencing the parent workflow, I would really appreciate the information! I've spent three weeks now on the same workflow trying to work around this limitation.
