Vendor WMS parameter FILTER not work with attribute parameters in STYLE

[guardeivid]

Hi, using [attribute] for example in COLOR or OUTLINECOLOR, and then a FILTER vendor parameter is applied from a client, it does not return any geometry

LAYER
  ...
  STYLE
    ...
    COLOR [color]

On the contrary, if the FILTER is applied and the layer has a color defined in hexadecimal or rgb if it works

I wonder if rendering through the QUERYMAP mechanism https://mapserver.gis.umn.edu/development/rfc/ms-rfc-118.html is dropping the attribute.

@jratike80 may be right although a QUERYMAP, depending on its STYLE definition, could ignore the attribute since in some cases another color is always used regardless. It should draw something however. Do you have a sample mapfile? What version are we talking? --Steve

Hi, I'm also experimenting this issue on versions 7.6 and 7.7-dev

Here's my mapfile and the data.shp referenced by it can be downloaded here
