Error trying to set Correlation Token at runtime for ReAssigning Task inside while loop.

Posted By:      Posted Date: October 08, 2010    Points: 0   Category :SharePoint

Hello Friends,

I have developed a custom sequential WF in VS 2010 using custom WorkFlow Content Type and ASPX forms.

Requirements are as below:

1.WF creates an approval task for User A. If User A rejects,then WF completes.
2.If User A approves,task is assigned to User B. If User B approves,then WF completes.
3.Is User A approves and User B rejects,then I need to ReAssign the task to User A.

I am facing problems in the 3rd point above.
I have a while loop having a Sequence Activity and the activities: CreateTaskWithContentType,onTaskChanged and CompleteTask are inside the Sequence Activity.

I am aware that the Correlation Token has to be set at design time in the VS 2010 WF Designer.

The issue is of dynamically assigning Correlation Tokens(Task Tokens) to the activities: CreateTaskWithContentType,onTaskChanged and CompleteTask which are inside Sequence Activity(Inside While Loop).

My Code:
CorrelationToken C_Token =
                 new System.Workflow.Runtime.CorrelationToken();
createTaskWithContentType1.CorrelationToken = C_Token;

I get the error:"This operation can not be performed at runtime" when trying to assign Correlation Token dynamically as above.

Can anyone please hel

Create task activity break out inside a While loop

Hi I have developed a sharepoint state machine workflow. I want to assign a same task to more than one users, but unfortunatly, I cannot give the attribute "AssignTo" to more users in the code, even like this:"this.workflowTask1Properties.AssignedTo = "mydomain\\user01;mydoman\\user02", that will result in an empty value to the attribure.So, I involved the createtask activity in a While loop so I can asign deferent user in each loop, but It's very stange,  the loop always stopped in the second time, does anybody have met this issue?I have referensed Amit's question:http://social.msdn.microsoft.com/forums/en-US/windowsworkflowfoundation/thread/b238978d-f330-420c-823e-b77b0e19414d?prof=requiredbut I have no define the "correlation refernce " in my workflow.my code is here:public SPWorkflowTaskProperties workflowTask1Properties;public int abc;...private void OnWorkflowActivated(object sender, ExternalDataEventArgs e)        {            ...           this.abc = 0;           ...        }...private void CreateTask1(object sender, EventArgs e)        { 

Passing Parameters to Execute SQL task which is inside a For Loop Container

Using a Create Task Activity inside a While loop



I have developed a sharepoint sequential workflow. It consists of a while loop, inside which there are 2 activities (in a sequence)-

1. Create task activity

2. Code activity

Code activity is used to set the test condition of the while loop.

The loop executes successfully on the first iteration. But on the subsequent iterations, an error occurs in the workflow.

My requirement is to create the task repeatedly as long as while loop doesnt exit. Is this possible? Any suggestions would be valuable.



Correlation Token & Create Task Woes


I've created a State Machine work flow.
In State1 I create a Task (Task1). 
The workflow then goes to state State2 and State2  goes  back to State1.
Now when State1 runs through creating Task1 again I get a correlation token error.
I would like it to create a new Task1.

I'm not sure how I should be going about this.
The Correlation Token for Task1 is set to 'workflowToken'.  Inside the MethodInvoking code for Task1 I set
Task1_TaskID = Guid.NewGuid();
It creates a task the first time the flow passes through State1. It's on the second time that it passes through State1 that it crashes.

Am I doing anything wrong?

Using Dynamic Property inside Html Helper with Razor fires an error



I have the following with Razor:

@Html.GoogleAjax(View.GoogleAjaxKey, new String[,] { { "jquery", "1.4.2" } })

And the I get a strange error:

  'System.Web.Mvc.HtmlHelper<object>' has no applicable method named 'GoogleAjax' but appears to have an extension method by that name. Extension methods cannot be dynamically dispatched. Consider casting the dynamic arguments or calling the extension method without the extension method syntax.

What is strange is that it works fine using:

@Html.GoogleAjax("123", new String[,] { { "jquery", "1.4.2" } })

I tried the following code line:


And the key is displayed just fine so the problem is how I use the value of @View.GoogleAjaxKey into Html.GoogleAjax.

Do I need to change something on my Html Helper? Here it is:

    public static MvcHtmlString GoogleAjax(this HtmlHelper helper, String key, String[,] libraries) {


Convert .docx to web page - "the converter cannot complete the task because an internal error occurr


I'm trying to convert docx files to webpages to be published in to a library elsewhere on our sharepoint site. At first I was having no problem, the files were converting, however more recent files have returned the error: the converter cannot complete the task because an internal error occurred

I've tried writing, uploading and converting a simple docx file, and this works which has led me to believe that the problem is something in the docx files that i'm trying to convert. So i tried using word07 to clean the documents up by clicking Office button>prepare>inspect document then removing all the metadata, custom xml etc from the files resave, upload and convert, but still no joy.

I'd simply rewrite the document but the problem is that there are a lot of them.

Any ideas what's going wrong?

XML Task error message hexadecimal invalid character

I am developing a SSIS package to add data from an XML file to an existing SQL Server table.  I have completed several similar projects, but on this XML file I am getting the error from the Data Flow tab between the XML Task and Data Flow Task: Error: 0xC002F304 at XML Task, XML Task: An error occurred with the following error message: "'', hexadecimal value 0x15, is an invalid character.

How to detect that a Data Flow Task has failed (from inside a custom componet)

Hi, in the PostExecute Method of a custom component i would like to check if the Data Flow Task has been failed. Is that possible? Also it would be great to be able to check if this custom component already got all data or has been marked as "green".  Thanks, Dennis


I'm currently experiencing a spinloop wait type with command of Unknown Token. The issue occured when I copied DB filed from another server and attempted to attach it -using the SSMS wizard - to the affected DB. The attach failed due to an OS permission error but the database engine - for no clear reason - mounted the DB in a Recovery/Read Only mode; the transaction did not rollback. This rogue DB cannot be altered, dropped, detached, etc and KILL command fails against the culprit SPID. In the DB log there is a stack dump at Location:  "logmgr.cpp":5527, * Expression:  !(minLSN.m_fSeqNo < lfcb->lfcb_fSeqNo). And the errors: Error: 17066, Severity: 16, State: 1; Error: 3624, Severity: 20, State: 1.

Execute Process task - On Error (i want to override the error message)

Hi, In my package I am calling one exe to copy the files from local folders to SFTP. I am using a execute process task and I am passing the parameters like (address, username, password,....). The exe and syntax are given below. SFTPCopier.exe <<machinename>> <<username>> <<password> <<local directory path>> The problem is when the exe is failing to copy the files to SFTP due to some reason, the SSIS package is outputting the entire command in the log information (including the username & password). I dont want to write the password in the log information. I want to remove that password from the log information when an error occured in the execute process task. Can some one please tell me the way to override the message? Can I put a on error handler for that execute process task and use a script task to modify the "ErrorDescription" variable? Will that works? Thanks in advance.

Visual Web Developer 2008 Express - JScript runtime error

I've noticed in Visual Studio 2008 and Visual Web Developer 2008 Express that several, dynamic JScript files are being generated at runtime.  When I run my project in "debug mode," and then I attempt to close the browser, I get the following error: "Microsoft JScript runtime error: Object doesn't support this action" The error occurs in a JS file called "jquery-1.3.2.min.js?77[dynamic].  This file is not part of my project, and I don't know where it resides. In Solution Explorer, under "Script Documents" > "Windows Internet Explorer", there are several other dynamic js files that are only appearing at runtime... What feature is causing these JS files and the JScript runtime error, to be dynamically generated at runtime?
