Trouble with OAM Change Attribute Workflow

Question

We're trying to setup a Change Attribute workflow but cannot get the Request to Modify button to appear on the modify profile. Our first test was to:
1) Assign Modify rights for Full Name to anyone & anonymous roles
2) Using QuickStart, generate a change attribute workflow for Full Name
3) Login as orcladmin
4) Open up a user profile for modification
We're assuming the Full Name field should no longer be editable, but should show a Request to Modify button on its right. This doesn't happen. The field is still editable and no button appears. Are we missing something?

Answer 1

Thanks for the help. Having reinstalled OID/OAM a bunch of times to properly add our custom user object, nothing seems absurd. I tried running through your steps, but I'm still not getting the workflow button. I've customized create and delete workflows properly, but the change attribute is a mystery.
I did the following:
1) Selected a custom attribute in Attribute Access Control
2) Changed its read access to Anyone
3) Saved
4) Changed its modify access to Anyone
5) Saved
6) Added a new Change Attribute workflow for the custom attribute
7) Action #1: Request, added Anyone as participant and saved
8) Action #2: External Action, selected attribute is the custom one
9) Action #3: Commit
10) Saved and enabled the workflow
11) Restarted the Identity server
12) Picked a user
13) Opened his user profile
14) Clicked Modify
The custom attribute is still editable and has no Request a Change button.
