[mapserver-users] Legend for a layer with filter

[Subha Ramakrishnan]

Hi,

I want to know if it is possible to generate a legend for a layer with a 
filter.
I am getting a blank response with a mode=legend for this layer.
I tried passing the parameter that i am using in the filter, in the 
request but didn't work either.

This is the layer in the mapfile:
layer
  name filterlayer
  connectiontype postgis
  connection "user= username dbname=db password=passwd host=localhost"
  group world
  type polygon
  status on
  class
    style
      width 3
    color 170 153 175
    outlinecolor 000 000 000
   end
  end
  filter 'id IN (%pid%)'
  data "topology from dbtable"
  transparency 65
  end

Thank you.

Regards,
Subha
