Steps to reproduce:

1. Add two pages (one with a Web Content Display portlet, and the other an Asset Publisher)
2. In the WCD portlet, add a basic WC
3. In the AP portlet
   • Configure the Asset Link Behavior to "View in a Specific Portlet"
   • Flag the "Set as the Default Asset Publisher for This Page" checkbox
4. At the AP portlet page, click Edit next to the WC article
   • Click the Display Page link on the right menu > Display Page button > Select the AP page > Click Publish
5. Click Edit by the WC article again
   • Display Page > Click the link below the Display Page button (see DisplayPageLink screenshot)

Expected result:
User will be directed to a page with the WC article displaying.

Actual result:
User is directed to a UI error (see ...UIError screenshot).

NOTE: Not an issue on 6.1.20.
