This sounds like a big bug. Has it been reported as one?

OK.

Now for the observation. I had forgotten about the "auto_actions_for :owner,
:index" (although I frequently use "auto_actions_for :owner, [:new, :create]")
and coded the following into my owner model:
show_action :possessions
def participants
hobo_show do
hobo_index @conference.participants.apply_scopes(
:search => [params[:search], :name, :affiliation, :country],
:order_by => parse_sort_param(:name, :affiliation)
)
end
end
Then I used the <index-page>, with a fixed <new-link:>.
Overall, this seems to be less code then using "auto_actions_for", but it
looks like it might be a wash if the above mentioned bug was fixed.
