Problem validating StringBuilder fields in SharePoint 2010 Custom Workflow Validators

Posted By:      Posted Date: October 11, 2010    Points: 0   Category :SharePoint

One of our custom SharePoint Designer workflow activities, which have always worked fine in SharePoint 2007, fails to validate.

This appears to happen when a Workflow Activity that contains a StringBuilder field also contains a lookup variable.

<FieldBind Field="CustomCode" Text="this code" Id="1" DesignerType="StringBuilder" />

For example when we store the following in this StringBuilder field

"Today's date = [%Current Item:Transaction Date%]"

This field returns 'null' in the ActivityValidator. As a result we cannot validate its contents.

Problem with Update of Sharepoint Taxonomy Fields in custom developed Content Types

Dear all, we developed an solution on sharepoint 2010 for one of our customers with custom lists and content types with fields from the managed meta data store. As recommended we developed everything in features & solutions so that easy deployment is possible. Adding metadata to the termstore seems to work without problems, but today we stepped over an confusing issue: Our customer changed the default label of an term in the metadata term store, but the label did not change in listviews and detailviews of items in the specific sitecollection. In editview we see the correct label. After searching a while we discovered the connection between the sitecollection and the term store, the hidden Taxonomylist (/Lists/TaxonomyHiddenList/AllItems.aspx) in the sitecollection, which seems to map the terms. After testing we discovered that the term/label did also not change in the hidden taxonomy list. The Timerjob “Taxonomy Update Scheduler“ is running hourly with success and we also tried to start the job manually, but the label did not change in the hidden list. Also there are no errors in the logfiles in verbose mode. We also tested to create a managed metadata field manually, put it in a list and after that, changed the label. For whatever reason the update of labels on manually created fields works without a problem. Our lists, content types etc get created pr

Upgrade Sharepoint 2007 Custom State Machine/Sequential workflow to SharePoint 2010



What's the path for upgrading the SharePoint 2007 Custom State Machine/Sequential workflow to SharePoint 2010 when the current SharePoint 2007 environment is upgraded to SharePoint 2010 by an inplace upgrade?

What's the typical estimate time for upgrading SP2007 custom workflow to SP2010 custom workflow?  My gut says 40 to 80 hrs or even less than that, what’s your thoughts?

FYI...I tried to upgrade the SharePoint custom workflow built using visual studio 2008 in SP2007 environment to visual studio 2010 solution/project in SP2010 environment, I got the error messages to refer the following dll's

Microsoft.SharePoint.dll and Microsoft.SharePoint.WorkflowActions.dll

Even after referring the new dlls still the workflow design doesn't show up in the canvas...still work on this to fix mean while want to know the experts insights on this.

custom workflow visual studio 2010 for SharePoint 2010


Hi Everybody,

I have written a custom workflow in visual studio 2010 with custom Task Edit Form which is associated with content type and that content type is in turn associated with Task List. When an item is created in the target list to which my custom workflow is attached, a task item is created when I click on that task item it loads the custom Task Edit Form page where I have defined the UI and on click of Approve button I just Alter the task by using method SPWorkflowTask.AlterTask(this._TaskListItem, taskHash, true); when this line executed it executes the Task Changed invoked method where I am taking true and false value from the UI and updates the corresponding metadata in target list.

The problem is when I create 2 target list items their workflow status becomes pending and when I approve one of them, both the items get approved i.e. Task Changed event get called 2 times and both line items workflow status become completed. The task list item corresponding to one approved get 100% completed but other one did not show its completion.

problem using custom membership provider in sharepoint 2010, please help!



My company developed a custom membership provider using .net framework 4 which causes the problem. As you know, all web application in sharepoint 2010 is running on .NET framework 2, so when a web application is configured to use our .net 4 custom membership provider, .NET CLR version 2 is loaded to run the web application but our membership provider assembly binds to .NET CLR version 4. So it is not surprising to see the following exception:

Could not load file or assembly '[our membership provider assembly]' or one of its dependencies.This assembly is built by a runtime newer than the currently loaded runtime andcannot be loaded.

Logically, there are two ways to solve this problem, but neither of these ways actually works.

1. Change the application pool under which the web application runs to use .NET 4 rather .NET 2. But this causes a lot of web.config exceptions. I don't quit understand those config exceptions because in asp.net it's framework backwards compatible.

2. Redirect our membership provider assembly to be executed under .net framework 2. But this way also doesn't work because if our membership provider assembly uses some classes available only in .net framework 4, that part of code has no way to be executed.

Unable to create task using Custom task Process Action in Sharepoint Designer 2010 workflow

Problem : In Sharepoint Designer 2010, we are working on creating reusable workflow.
In workflow we are using "Start Custom task process" action. It has been observed that,all of the sudden it behaves weirdly. It creates task but without any number appending to taskform.for eg. when we create task it generally shows "Start Task(1) process on Current Item with these users" However now it does not provide any number with Task. It shows "Start Task process on Current Item with These users"
In task form , it does not allows to add task forms fields from existing fields nor allows to create outcomes.
Thus we are unable to create any new workflows or edit and enhance exisitng workflows in the site.This is showstoper for project. Client wants to use sharepoint designer exclusively to develop workflow.
When we tried to create workflow (Sharepoint designer) in a new site with new list it allows us to create custom tasks process. 
Resoultions approaches done so far.
1) Took backup of site on local box from Server and tried to create custom process task but not able to do it.
2) On Server removed all unwanted workflow status columns from the tasks list but still not able to create custom process task 
3) Took backup and t

SharePoint 2010 Long Starting if start workflow programatically


In SharePoint 2010, I'm starting workflow #2 programatically from my workflow #1. See code below:

					SPList currentList = web.Lists[new Guid(ListId)];
					SPListItem currentListItem = currentList.GetItemById(ListItem);

					//resolve any lookup parameters
					string workflowId = base.ProcessStringField(WorkflowIdentifier);

					//find workflow association by name
					SPWorkflowAssociation workflowAssoc = currentList.WorkflowAssociations.GetAssociationByName(workflowId, Thread.CurrentThread.CurrentCulture);

					if (workflowAssoc != null)
						//start the workflow
						SPWorkflow workflow = site.WorkflowManager.StartWorkflow(currentListItem, workflowAssoc, workflowAssoc.AssociationData, SPWorkflowRunOptions.Synchronous);

And workflow #2  will hang with Starting status (1-10 minutes), Then the workflow #2 status would be modified  to Completed.

I couldn't find how to start the workflow # 2 immediately and complete immediately without several minutes delay
