Thanks Lucy! You saved me a lot of time wondering what the heck I was missing>

Hi,

I am facing similar issues.

When I try to attach the workflow to the item in the document library, the workflow status shows “Error occurred”. I searched in the internet and find out that this occurs when there is the problem in the code (http://blogs.msdn.com/sharepoint/archive/2006/11/30/developing-workflows-in-vs-part-6-deploy-and-debug-your-workflow.aspx?CommentPosted=true#commentmessage).

Then I tried to comment all the code in below eventsà

private void onWorkflowActivated1_Invoked(object sender, ExternalDataEventArgs e) {}

private void codeActivity1_CodeHandler(object sender, EventArgs e) {}

After that I tried to run the workflow, the status is shown as “Completed”. This is when there is no code in the above events.

After this then I modified the events within the below codeà

private void onWorkflowActivated1_Invoked(object sender, ExternalDataEventArgs e)

{
workflowId = workflowProperties.WorkflowId; //initialize the id


}

private void codeActivity1_CodeHandler(object sender, EventArgs e)

{

System.IO.Stream strm = new System.IO.FileStream("c:\\shashwfl.txt", System.IO.FileMode.OpenOrCreate);

workflowProperties.Web.Lists["Tasks"].WriteRssFeed(strm);

}



Again I got the same error as “Error occurred”. I think some important code is missing in the above events, but don’t know what.

Can you have any clue regarding this?

Thanks
Shash

do we need to provide some fix here?

I don't suppose anybody knows where the KB Article has gone? I'm encountering the same issue (NullReferenceException when editing a page) but the KB article has gone missing.

Thx,

Hello, sorry for my late reply, i had a short holiday. :)

Shashwat, in regards to your comment, this does not relate to the bug above, but seems to be code related. please try to debug the newly added code, this should give you an error description in visual studio when the exception occurs.

H.Y., In relation to the KB article, as stated above the article has been taken offline, probably it is still in review at Microsoft or not yet fully tested, they do not release the article for the public until it's fully tested and approved. but if you give Microsoft Support a call and mention the number they will provide you with the fix.

Good luck!

Yes Lucy,

You were very much rite.After writing lot of codes in Sharepoint i found if your custom workflow after running shows status as "Error Occured", it certainly means that something is wrong in the code you have written.Please reveiw your code if the status is "Error Occured".

Also I have one more problem now.

I have created an App.config file for my Workflow.When builded it gives me a file name as Workflow.dll.config.
I need to add this App.config in the GAC so that when the Workflow DLL is in GAC it looks at the appropriate App.config in GAC too.

Problem is that App.config is not getting added to the GAC.
any solutions?

Shashwat
