And how do I access a combobox value in a listview? I'm trying to check 
value of another cell in a row in a validation block but fail to. It 
seems that I can access only ComboCol and it doesn't have a 
"active_text" method.
I'm lost. :)

Here's my code:

self.renderer(:get_formats).validate_block = Proc.new { | value, row |
  if row[:formats].active_text == ""
    @yt.get_formats(row)
    row[:formats] = VR::ComboCol.new("Choose", 
*@yt.videos[row.to_s.to_i].formats)
  end
}

It returns with error:
undefined method `active_text' for #<VR::ComboCol:0x00000002eac7c8>

Cheers,
k
