Unknown operator 'may_set_owner'

[Andrew Schulman]

TracWorkflowAdmin 0.12.0.4, r16358, in Trac 1.2. When I visit admin/ticket/workflowadmin, below the table I get a yellow error box with the message:

Line 6: Unknown operator 'may_set_owner'

And the graph doesn't appear, although I have the graphviz plugin (1.0.0.9dev) installed and have verified that it's working in other parts of our wiki. If I click on Update, it returns with no change. See the screenshot.

Appears it should have been fixed in r16032. What is your [ticket-admin] operations option set to in trac.ini?

[Andrew Schulman]

Hm. In trac.ini I have:

[ticket-workflow]
create_and_assign.operations = may_set_owner

So that seems to be the trouble. If I change the value to set_owner, the problem goes away.

But I don't have a [ticket-admin] section. Didn't know I needed it, and I can't find any documentation of it. Can you suggest a value for operations?

[Ryan J Ollos]

You can find documentation for [ticket-admin] on TracIni in your Trac installation. You can see values for your Trac installation on the /about page when you have TRAC_ADMIN or CONFIG_VIEW. If you haven't set a value then you'll be using the default, which should be fine.

A duplicate of #12933.

If you don't need to configure [workflow-admin] operations, remove the option from your trac.ini. Otherwise, append may_set_owner to the option.

And the graph doesn't appear, although I have the graphviz plugin (1.0.0.9dev) installed and have verified that it's working in other parts of our wiki. If I click on Update, it returns with no change. See the screenshot.

The graph isn't rendered due to errors of the workflow.

[Ryan J Ollos]

Oh, right. Sorry I mistakenly said [ticket-admin] rather then [workflow-admin].

Got it. I reset [workflow-admin] operations to its default, and the problem is fixed. Thank you for your help.
