end

#valid_activitiesObject

The activities to be displayed at the content block.

We need to build the collection this way because an ActionLog has polymorphic relations to different kind of models, and these models might not be available (a proposal might have been hidden or withdrawn).

Since these conditions can't always be filtered with a database search we ask for more activities than we actually need and then loop until there are enough of them.

Returns an Array of ActionLogs.
