Send a notification email to users when blog post is first approved but NOT on subsequent edits/approvals. Using a 2010 wf triggered by an item change.
Added a yes/no helper field ("email sent") to check if an email has already been sent.
Workflow runs but no email is sent. No error.
When I tried that I got a validation error about "An IfElseActivity must have at least one child of type IfElseBranchActivity.)". Wf still runs but doesn't send email.
