[mapserver-users] error with getfeauture info for postgis tile index

[Lassche, M.R (Ronnie)]

Hi All, 

I have a tileindex which is based on a postgis layer and everything works well. 
I've put the 2 layers in one group in order to be able to get information from the index layer available for the users. When I use a shape file as an index this works fine. But when I use a postgis layer as index the following error occurs. 


==error== 
msShapefileOpen(): Unable to access file. (/mapserver/www/cgi-bin/maps/_tmk-index) msShapefileOpen(): Unable to access file. (/mapserver/www/cgi-bin/maps/_tmk-index) msShapefileOpen(): Unable to access file. (/mapserver/www/cgi-bin/maps/_tmk-index) msShapefileOpen(): Unable to access file. (/mapserver/www/cgi-bin/maps/_tmk-index) 
==== 

It seems mapserver expects a shapefile and can not handle the postgis index layer for the getfeatureinfo. 

Does someone has any idea what can be wrong? 

Thanks in advance, 

Ronnie
