Hi,
I would like to ask you a question concerning the ServerMapquery class.
is the OGR connection managed?

In fact I have problems with querying. First I 'll expose you the matter :
I want to  show datas, trough a Query, of a layer in MapInfo(Claritas) 
Format.
Here is the code in my Mapfile :

LAYER
   NAME            "PPE"
   CONNECTIONTYPE  OGR
   CONNECTION     "N_PPE_AEP_068.TAB"
   TYPE            Polygon
   TEMPLATE "ttt"
   PROJECTION
     "init=epsg:27582"
   END

   METADATA
id_attribute_string "Nom_UGE|string"
   query_returned_attributes "DUP"
   END

   CLASS
     NAME         "PPE"
     SYMBOL       "circle"
     SIZE         50
     COLOR        100 255 100
   END
END


LAYER
   NAME "PPE_hilight"
   TYPE POLYGON
   CONNECTIONTYPE  OGR
   CONNECTION     "N_PPE_AEP_068.TAB"
   TRANSPARENCY 50
   CLASS
     STYLE
       COLOR 255 0 104
     END
   END
END


When I select once a area with the information tool, I can see the query 
results.
But if I try to do another selection, I have this message on the screen :

"Layer to center on has an unsupported connection type: 4"

This message is generate by the ServerMapquery class. I saw nowhere in the 
code the
Mapscript constant, MS_OGR, does it mean that the OGR connection isn't 
avaible for query. Then
why does it work one time and no more after?

cheers,


Frédéric Bauer
