Avoid firing OnWorkflowItem changed for changes made by the workflow

Question

I have a state machine workflow that responds to changes in a list item. The workflow also updates the list item; is there any way to avoid firing the OnWorkflowItem changed event when the changes were made by the workflow?

Answer 1

use the List item's.SystemUpdate() method instead of Update().

So I found a workaround for this, but it's pretty ugly, hopefully someone has a better answer.

Rather than having one state do an update and then wait for the event, I split it out into two states. The first state updates the list item, catches that on change event, and transitions to the second state which waits for the a change from the user.
