2. Add a Community Site
3. Unflag Enable propagation of changes from the site template Community Site
4. Click Staging > Activate Local Live
5. Flag Enabled on Public Pages
6. Click Workflow Configuration
7. Select [Single Approver (Version 1)] next to Page Revision
8. Add a Site Role
   Name: Staging Admin
9. Click Define Permissions > Site Administration > Pages > Site Pages
10. Flag all the Action checkboxes
11. Add a Site Role
    Name: Web Content Creator
12. Click Define Permissions > Site Administration > Content > Web Content
13. Flag all the Action checkboxes
14. Click Define Permissions > Site Administration > Applications > Web Content Display
15. Flag the Action checkbox > Save
16. Add a User
    Screen Name: contentcreator
    Email Address: [email protected]
    First Name: ContentCreator
17. Set a password
18. Click Sites under User Information
19. Click Select link > Community Site Test > Save
20. Click Roles under User Information
21. Click Select link near Site Roles > Staging Admin
22. Click Select link near Site Roles > Web Content Creator
23. Navigate to Community Site Test
24. Assert staging
25. Sign Out
26. Sign in as [email protected]
27. Navigate to Community Site Test > Staging
28. Add Web Content Display portlet
29. Click Staging > Submit for Publication
30. Click Publish to Live > Publish

Expected result:
ContentCreator should not be able to publish to live, as another user must approve the publication first.

Actual result:
ContentCreator cannot publish to live, but the Publish to Live window displays both a, “Your request completed successfully” message and “Failed” message. When the user clicks on “Details?” next to the “Failed" message the following error message is displayed:

An unexpected error occurred with the publication process. Please check your portal and publising configuration.
com.liferay.portal.NoSuchLayoutException: No Layout exists with the primary key 0

These conflicting messages are confusing.
Either a message should be displayed explaining the the user ContentCreator does not have permission to publish directly to live, or the Publish to Live button should not display at all when the current user does not have permission to publish to live.
When navigating to the live site, the Web Content Display portlet is not published as expected.
