Filter Calendar by User - Using the Action Framework

I see, OK, thanks. I’ve gotten this approach to work so that users can choose a picklist value from a field, and that filters the primary page model(s) correctly. And I can remove the condition with a “Clear” button as spelled out above. Very nice!

However, the last part of the “clear” actions, where I need to blank out the picklist on the FilterModel row that is showing currently selected picklist value, doesn’t seem to work. The model does get “unfiltered”, but I can’t get the picklist to be “unselected” again (or changed to any other value, for that matter) by just creating an action that says “updated field on row to [blank]”. That action doesn’t seem to do anything.

(Sorry, I’d show a screencast, but it’s working with private financial data, so its hard to clean up.)
