• Type: Bug
• Status: Closed
• Resolution: Duplicate
• Affects Version/s: Master
• Fix Version/s: Master
• Component/s: Content Display Widgets > RSS Publisher widget, Widget Templates, ~[Archived] WCM > Publication
• Labels: None
• Fix Priority: 4

Steps to reproduce:

1. Add a page
2. Add RSS Publisher portlet to the page
3. Add a feed (assert behavior from LPS-67568)
4. Open portlet configuration
5. Under "Display Template", click "Manage Display Templates for Liferay"
6. Click plus button to add a new RSS ADT
7. Provide a name for the ADT
8. Click "RSS Feeds*" under "Fields" panel
9. Save the ADT
10. Return to the page
11. Open the RSS Publisher configuration
12. Under "Display Template", select the newly added RSS ADT
13. Save the portlet configuration
14. Return to view the portlet

Expected result: RSS Publisher portlet renders ADT successfully
Actual result: RSS Publisher does not display feed using the added ADT; error is thrown in console:

11:11:13,043 ERROR [http-nio-8080-exec-4][runtime:60] Error executing FreeMarker template
FreeMarker template error:
The following has evaluated to null or missing:

----
Tip: If the failing expression is known to be legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
