[Paul Everitt (paul-agendaless)]

Boy, now that we can see all the intermittent errors, we're filling M45 up pretty fast. Probably need to triage.

[Chris Rossi (chris-archimedeanco)]

Judging by the callstack, I'm guessing that someone entered the path to a page for one of the portlets in the edit_intranet view. Since we don't have a portlet for the Page content type, this broke the office homepage. Whoever did it realized their error and undid it, because everything looks pretty ok now.

The only fix I can think of is a validation check on edit_intranet view to make sure that the paths entered for portlets actually resolve to some piece of content and that the content is of a type for which there is an IIntranetPortlet adapter registered.

[Paul Everitt (paul-agendaless)]

Let's put this in M46 and get Carlos to do what Chris suggested: raise a form validation error for the user on Edit Intranet portlets. Let's also consider handling the exception and putting into the portlet something that says an attempt was made to point at an id that doesn't exist.

Yes, it's obvious that my goal here is to shut up the alarm. :)

[Carlos de la Guardia (cguardia)]

For consistency, the ComponentLookupError exception is handled and a text is shown in the portlet place indicating that the content referenced by that path is not a portlet. This is the existing behavior for when a portlet does not exist, in which case a portlet missing message is shown.
