SharePoint 2010 State Machine workflow delayActivity tip

If you’re using a delayActivity in your Visual Studio State Machine workflow, you are likely to want to use the InitializeTimeoutDuration handler to set the length of the delay.

An easy mistake to make is to think you could do the following:

private void DelayActivity_InitializeTimeoutDuration(object sender, EventArgs e)
        {
            delayActivity1.TimeoutDuration = new TimeSpan(0, 10, 0);
        }

However, this won’t work. This is because SharePoint will intialise a new instance of the delayActivity with the timeoutduration specified as default. To set the TimeoutDuration of your “actual” activity, you should do the following:

A common problem in designing workflows is how to make the workflow “sleep” for a period whilst users do (or don’t do) something. A common scenario is where you wait for some user input, but if you don’t get any by a certain time to continue the workflow in a different stream. You achieve this with a delay activity where you specify a timeout in the form of a Timespan.

The delay activity was broken in SP2007 which was then fixed with a Hotfix. Surprisingly, this remains kind of broken in SP2010 as well. That is to say, the delay activity never wakes up.
