WMS Highlight

Hi all,

I'm using GWP WMS and I'm trying to highlight some features using custom GWP WMS parameter (HIGHLIGHT and HLCOLOR) but it seems does not works.

This is my GetMap request:


In order to be sure about the id value i've execute a GetFeatureInfo over the object and this is the result:

< GetFeatureInfoResponse >
< FeatureKeysInLevel level="SDR_PDR" keys="1301"/ >
< /GetFeatureInfoResponse >

Some suggetions?
