Sharepoint Designer issue "could not deserialize object"?

Posted By:      Posted Date: August 31, 2010    Points: 0   Category :SharePoint
Hi there, I'm relatively new to Sharepoint in general but I've got an install of Sharepoint Foundation and I'm working my way through the book "Sharepoint 2010 Development." At any rate, I'm trying to create a workflow in Visio 2010 and then export that workflow into Sharepoint Designer 2010. However, when I try to import the .vwi file into Designer, I get a "Could not deserialize object. The type 'Microsoft.Office.Workflow.Actions.ApprovalTaskProcess' could not be resolved." This, of course, is because in Visio I have a Start Approval Process object.  Is this particular workflow item not available for Sharepoint Foundation? Does anyone have any idea why I'm getting this error? Any feedback is appreciated. Thanks, Jearod

Sharepoint Designer restore issue or perhaps BPOS permissions issue

Sharepoint Designer 2010 - Collect Data from User Issue


I am currently running Sharepoint 2010 Foundation and Sharepoint Designer 2010

I am creating a custom workflow where I am asking 1 user for input using collect data from user.  Following this I am asking a different user the same question using another collect data from user.

Since these creates 2 tasks (1 for each user) I wanted to store the information in the same column, but I seem unable to do so.  Each collect data from user seems to create it's own column even if you name both the same (you end up with 2 columns with the same name but different column id's).

Is there a way to point them both to the same column?  Is there a better way to do this?


More the less I am asking the both persons a yes/no question.  in my workflow if they both say yes I send an e-mail but wanted to have only 1 column in the vew to see the results on the tasks.

SharePoint designer program issue

I have a custom dataFormWebpart with filtering enabled on my page with SharePoint Designer.

When I save my code file, SharePoint designer adds empty lines in my code. My code file gets larger and it crashes when the size reaches really high. Right now, I find those empty lines periodically (maybe after 10 times of saving) and delete them before my code file becomes too large and crash. Is this a bug?

Outlook 2010 / Sharepoint authenthication issue


Hi all,

I'm using Outlook 2010 on Windows 7 64bit.

My company uses a hosted Sharepoint server (I guess it's Sharepoint 2010). There's a team calendar, which I would like to connect to my Outlook 2010. Linking it to Outlook works fine until it tries to update the calendar with the Sharepoint server. I shows the following error:

Error (0x80070005) when running the task "SharePoint": "You are not authorized to view the SharePoint list (team calendar). Contact the administrator of SharePoint site. HTTP 401."

So this tells me, I'm not authorized to connect - which is quite clear because Outlook never asked my for any username or password.

Funny thing is when I try to add an internet calendar (Right mouse click on calendars, Add calendar, Internet calendar) and use the url of the sharepoint list, it asks me for username and password, but then fails to add the calendar, as it isn't a webcal (which is OK).

BUT: As Outlook at this moment has the username and password, the exisiting Sharepoint calendar synchronizes correctly. This works until Outlook is being restarted.

Does anyone have an idea why I'm not asked for any authentication? Maybe there's some setting I haven't found yet? It works with trying to add the webcal any time when I start Outlook, but t

sharepoint 2007 indexing issue


when we do incremental crawl, the items in index start decreasing and the error count remains the same. so it is hard to find what is causing the index items to reduce. can anyone help please. i had to pause the active crawl because of this index item decrease.

I have checked the following:

1) there is no space issue

2) no credential issue

What I found a bit fishy is that:

1) in the log, i got ->

a)get REGKEY_FLTRDMN_MS_TO_IDLE, using default - _File:\office\source\search\search\gather\fltrdmn\fltrdaemon.cxx Line:323

b) Server Office Server Shared Services 6pls Medium Cache blocked for shared object '1dd1db1d-8a07-4e27-9249-b7d328818fa2' of type 'Microsoft.Office.Server.Search.Administration.SearchSharedApplication'

Trying to send email using Sharepoint Designer 2007 workflow and email enabled list


I have a a list that recieves email. I have few fields that shows me the originator: "E-Mail From" and "E-Mail Sender".

I am trying to create a workflow that will generate an auto reply to the originator but the SPD fails to recognize the email address in these two fields. It's either truncating part of it or uses the html ( href=mailto:Demo@DemoSomething.com) in the To field.

How can I implement this workflow scenario with SharePoint Designer?



I have a document content type and a library which contains this content type. here is what I want to do:

- when user creates a new document in this library, he will enter some user  names with people picker and then a message including some columns of the content type will be sent to that users. And then, at a certain date (lets say 1 day before a date that is one of the site columns) another email, a reminder will be sent.

2- How can I make it sent a reminder email 1 day before the date that is stored in one of the columns of the content type(current item)

How to Establish a Remote Web Site Connection in SharePoint Designer 2007


I am modifying a SharePoint site and so far so good.  Some of the objects were created using Visual Studio 2008 (C#).  I was able to modify these objects and implement them on the targete machine without issue.  The final step is to implement the ASPX pages that were modified using SharePoint Designer 2007.  These are aspx pages that are used to modify items in lists.  All the pages involved in this upgrade are customized.  I need to upgrade the target site with the modified version of these pages.  My intent is to copy the code from the page in the source site and past it into the same page on the target site.  I tried using the Remote Web Site connection tool in SharePoint Designer 2007 but received the following error message:

"Unable to open 'https://(site address)'.  Server Error:  Could not find a Web server at 'website'.  Please check to make sure that the Web server name is valid and your proxy settings are set correctly.  If you are sure that everything is correct, the Web server may be temporarily out of service."

I am not sure how to first check to see if the Web Server is temporarily out of service.  I would appreciate your input on how to verify this.

Background information of target machine:  WinServer 2008, IIS 7, Sharepoint (MOSS2007), site on port 80

SharePoint Designer: insert custom list not working anymore



Suddenly sharepoint designer decided today that it doesn't want to insert a custom list form anymore...
To be more specific, it doesn't work anymore in a site that uses the Microsoft budgeting and tracking template. In a website that uses an out of the box template, it still works.

It did work before, because I did it in other websites using the same template (it's broken there as well now).

Why oh why does SharePoint refuse to do this now?
I searched google and here on the forums, but all I could find was some issues after installing SP1, but we did that already long time ago and it was still working after that. I checked with our infrastructure guys and they didn't install new updates they say.

I also tried the solutions listed here: http://blogs.msdn.com/spdsupport/archive/2008/07/03/how-to-fix-custom-list-forms-will-not-insert-or-show-up-on-the-design-surface-of-sharepoint-designer.aspx
But they don't fix the problem.

So my problem is, I can go to Insert > SharePoint Controls > Custom List Form
I pick my list, content type and form type, I hit OK and... nothing happens.

How to create scrolling table for columns in a SharePoint Designer Data View


I have a fairly complex SharePoint Designer 2007 Data View they have added two more requirements.

1. Have the columns on the right side be able to scroll left to right as there is a large number of columns, while the first 3 columns on the left side stay locked in place.  This is only one list not two, and because of some other requirements I have it must remain to be just one list.

2. Then they also need to have scrolling up and down of the entire list with the headers locked in place.

The first requirement is more important than the second, but preferrably I need to do both.

I am new to XSL so not familar with the syntax. Is this something I can do on a custom Data View? Does anyone have any examples of how?

I have a drawing that show how it needs to look but I don't see an option here to upload a graphic.

So here is a link to my graphic example uploaded to my blog area: http://lindachapman.blogspot.com/  or just the image here: http://4.bp.blogspot.com/_aB01ue__NvQ/TGL42MOvrGI/AAAAAAAAAA4/c3xP4uCy4BU/s1600/Scrolling.png
