What about SharePoint Designer??? When and where will it be RTM'd. I'ts not part of any of the Office 2007 suites:(

Please release Office Sharepoint Server 2007 on eOpen downloads Volume licensing site!

spfreak — Tue, 21 Nov 2006 01:11:23 GMT

If there is any way to push to have this put up on the volume license site which is accessed through the eOpen site it would be mucho appreciated!

I am looking to deploy a server right away and I have the license but Sharepoint Server hasn't been made available yet.

Interestingly enough, BobC (the previous commenter) may be interested to know that Sharepoint Designer has been released and does appear for me on the download site associated with eOpen.

Now I just need SharePoint Server to show up as well!

MOSS 2007 on eOpen downloads please

spfreak — Tue, 21 Nov 2006 01:30:48 GMT

I noticed Groove Server was put up but no MOSS :\

I guessed at what the url would be for the MOSS download based on the url for Groove Server and guessed correctly!

I was so excited that I might be able to finally grab MOSS RTM but alas even though it looks like the page has been setup the actual file was not present.

https://www.microsoft.com/licensing/servicecenter/downloads/ProductDetails.aspx?pcode=OFPSPS07&pfcode=OFP

above link works but download file which appears to be named 'Office SharePoint Server 2007 (X12-34619).IMG' was not found :\

(entire download link is: http://vl.download.microsoft.com/dl/download/release/Office%20SharePoint%20Server%202007%20%28X12-34619%29.IMG?lcid=1033&__gda__=1164125573_fbeb08b9748e0954065e2562dd92b314 )

If there's anyway to expedite posting the file it would be tremendously appreciated!

Great thread, Eilene! Can you address the following topics at some point during this series?

* potential pitfalls relating to simultaneous workflow instances on the same item

* how workflow instances and item versioning interact (and related pitfalls, if any)

Thanks!

re: Developing Workflows in VS: Part 1 - Workflow Objects and A Crash Course on Mechanics

Eilene Hao — Tue, 21 Nov 2006 23:28:20 GMT

Hey BAG,

The only major pitfall I can think of for having multiple workflow instances running on an item are if they manipulate the same columns and may step on each other's toes. For example, if you have a workflow A that sets some approval bit on an item, and another workflow B that sets the same bit, B may overwrite the value that A put in. So when you plan your workflow and which list it's going on, make sure you understand what kind of conditions like this exist and whether or not they are ok.

In general, workflow doesn't have any special interaction with versioning; workflows just run on the latest item, kind of independently of the version. So if you save a new version of the document while a workflow is running, the workflow doesn't change (unless you programmed it to respond to item changes in general).

The special case for workflow and versioning is the content approval setting for workflows on lists with major/minor versioning enabled. (i.e. on association, you can check the "Start when a major version is published" box. Note: Only one workflow can be the chosen one for a list;)) This will take you to an initiation page when a version is published, and you can start a workflow thru the initiation page. If the workflow is already running, publishing a new version will cancel the workflow.

Hope this helps. Let me know if you have more questions.

Carlos Cardoso — Wed, 29 Nov 2006 13:12:44 GMT

I've read your posts about dehydrating and rehydrating a workflow instance and I created my own custom very simple workflow with a log activity and a Delay.

The problem is that once the instance is serialized it never wakes up again. Even setting its sleep durantion for 1min it will still in progress after hours until it be canceled.

Maybe it lacks something to be setup to fire the wake up event or something like that but I few that it is not right.

Is there a service or anything else that should be in place so the event gets fired and my workflow instance wakes up and completes successfully?

Hi:

I am struggling with given tasks a unique set of permissions.

Basically, my workflow assign a task to a certain persion. This task is being added to the "Tasks" web part.

In my code of the workflow (workflow.cs) I want to manupulate the task permissions so that only certain people will be able to view the task.

How do I do that?

Hi Eilene,

When a tasks is assigned to aspecific user, he should teh only one who can access this task (view or edit teh task). But what is happening is that everyone can access everyone elses tasks even after adding the following lines of code:

this.AssignTask.SpecialPermissions = new System.Collections.Specialized.HybridDictionary(); //AssignTask is the name of the CreateTask activity

this.AssignTask.SpecialPermissions.Add(this.taskProperties.AssignedTo, SPRoleType.Contributor); //taskProperties is the variable bound on the TaskPropertied of the CreateTask activity

But actually it isn't working. Kindly note that teh workflow is a state machine model.

Waiting your soonest reply,

Thank You,

Zeina

I can create a List with anonynous access enabling users to add new items requiring content approval, this works fine and after adding an item they return to the list page. The problem starts when I add a workflow to the list the new item is added but the user instead of returning to the list page gets an

"An unexpected error has occurred.

Troubleshoot issues with Windows SharePoint Services." Page I removed the workflow and checked the list but now the only confirmation is the above error and so I have to recreate the list from scratch to work.

Any Thoughts.....

Regarding the Workflow History Log.

Is it possible to set a condition that looks for the workflow in the history so that things are not done twice? For example, I have workflow that runs every time an item is changed...wish I could only run it if a field is changed...anyway if a particular field is not blank it causes an update in another list. But if this is already done - then the result would be bad.

Can I use the history log to check to see if it was done?

Sharepoint Workflow developement in Visual Studio

CA_Dave — Thu, 20 Mar 2008 04:31:24 GMT

I cannot find anything that spells out whether or not I need to install Visual Studio 2005 on the WSS 3.0/MOSS server or not. My SysAdmins really don't want VS on the production server and I don't really want to have to ask Management for MORE funds to pay for extra Windows Server AND MOSS licenses for a developer environment. Its all starting to add up.

I have created development web apps and site collections in MOSS and WSS which function well with SPD but Visual Studio does'nt want to start the SharePoint designer tools and templates without MOSS/WSS being present. Surely VS does'nt require MOSS or WSS to be present locally.

I have been creating many workflows in Workflow Designer and everytime I use the "Set a field in Current Item" or "Update list item" actions, many instances of that workflow runs upon item creation or edit - like an endless loop of the same workflow.

Anyone ever experience this before?

Do you know if it is possible for a workflow to use more than one task form? Obviously each would be registered in workflow.xml but if it is possible, how does the workflow know which task form to use and when?

Redd — Thu, 19 Jun 2008 15:07:15 GMT

I have a workflow developed and in production.The problem is when i upgrade the workflow by adding new tasks and deploy the new worklfow on the deployment site the already In Progress items dont move forward where as a new item from starting can walk through the changes that i made in the worklfow.

What could be the reason?

re: Developing Workflows in VS: Part 1 - Workflow Objects and A Crash Course on Mechanics

MarkusT — Mon, 23 Jun 2008 12:58:51 GMT

Reply to Redd:

You can not update a workflow, where there are runnin ginstances, because the workflow engine stores binary information about the workflow and if this signature does not match, the workflow starts a new instance of the 'modified' workflow. There is some incomplete information what you have to do in such a case. The base line is, that you have to create a complete new workflow (new GUIDS, new feature, new names) and place this workflow for example with the name Workflow V1.1 on the list or content type. Then you have to set the old workflow in 'no new instances' mode.

re: Developing Workflows in VS: Part 1 - Workflow Objects and A Crash Course on Mechanics

chandrika — Fri, 11 Jul 2008 16:33:00 GMT

Hi Richard Jacobs

ypu can use more than one task form in workflow.

give you task forms urn's in the workflow.xml file as

<Task0_FormURN>urn:schemas-microsoft-com:office:infopath:TskForm1:-myXSD-2008-05-15T04-42-13</Task0_FormURN>

<Task1_FormURN>urn:schemas-microsoft-com:office:infopath:TskForm2:-myXSD-2008-05-15T04-42-13</Task1_FormURN>

In the code:

in create task method invoking

you can use

"createTask1_TaskProperties1.TaskType" to set which form should be displayed to which user.

createTask1_TaskProperties1.TaskType=0

will refer to first form

when you set

createTask1_TaskProperties1.TaskType=1;

then it will refer to second form.

Thnx for the reply MarkusT.

I knew abt this workaround but there are many such In Progress Tasks on the production site and we need to make changes to the workflow.We should also keep in mind that the older In Progress items use the changes.

I am havin a try on assembly redirection which may break this jinx

Hi Redd, I think I have the same problem. My workflow is in production. There are some instances in progress. I then have a need to upgrade it to newer version. I did change GUID and name but still after deploy it, I can't access tasks created by previous version. I get "Unknow Error" while clicking on those tasks. I am still trying to solve it. Please share me if you did solve your issue.

Could anyone else through some light?
