I've got a fix on the issue. It turns out that that method in question was
being overridden in a helper method associated with a different model (one
to many). I removed the column_attributes(column, record) in the associated
helper method and I got the page to render. This appears to be a method
chain error where my Webcast record was being passed through the
TwitterFeed helper method.
