When someone clicks "previous" on the last page of my multi-page form, the user goes back to the previous page as expected. But the 'Approved' workflow for the form is also triggered, in my case causing confirmation emails to be sent as if the form was submitted.

This fix http://issues.umbraco.org/issue/CON-209 did not work for me (I changed Forms.cshtml to implement it). I can see the value of "PreviousClicked" in the page source, it gets set to "clicked" when Previous is clicked, but the workflow is still triggered. 

This bug causes heaps of extra mails to be sent. 

Any suggestions? Anyone else with the same problem perhaps?

Edit: Contour 3.05 on Umbraco 4.9.0, form is rendered using Razor.
