problem with wms getfeatureinfo request and time indexed files

[fred]

Hello, I am facing a possible bug whith a WMS GetFeatureInfo request. The accessed data are time dependant images. As a consequence, I use an index by setting the TILEINDEX attribute in the mapfile. When using such an index whith the above mentionned request, MapServer returns as much results (all the results are the same) as images referenced in this index containing the requested geographic point instead of only one (only one image is asked). I attach to this ticket the mapfile, the index and the images. To reproduce this, please copy these files in the same directory and try the following (what I call the first image is the one of 2010/09/02 ie AERONET_Skukuza.2010245.terra.2km.tif, the second one is the one of 2010/09/01 ie AERONET_Wits_University.2010244.terra.2km.tif) :

GetMap request with the first image -> OK
