[Markaby] issue with acts_as_dropdown

I’m using Markaby to convert a standard form witth selects. Can someone
tell me why this doesn’t work?

tr do
td.formLabel do label “Owner” end
td do select( ‘task’, ‘owner_id’, capture( Owner.to_dropdown)) end

This code works just fine:

Owner <%= select 'task', 'owner_id', Owner.to_dropdown %>

But, the Markaby conversion doesn’t?

I’m sure I’m missing something simple, but starring at intensely doesn’t
seem to be solving anything. :slight_smile:
