QueryByPoint problem

[Stéphane RIFF]

Hi,

I want to query my map with QueryByPoint layer function.
The problem i face is :
  my map projection is esri:27582
  i have a layer which projection is epsg:4326 (the layer i want to query)

To get coordinate from mouse click i use pix2geo function which is base
on map projection
so i get click coordinate in esri:27582.
When i use queryByPoint it returns no results.
My question is do i have to reproject my point in epsg:4326 before doing
query
or does mapserver handles it by itself ???

Thanks
