TileIndex & Raster Images Problem

[C Gould]

Ed
It's the first case, and I can create the error just as you describe.

My layer defs are like this:

LAYER
        NAME "ASubject"
        GROUP "PRM"
        TYPE RASTER
      TILEINDEX "C:\MyPath\ASubject.shp"
      TILEITEM "location"
      MAXSCALE 100000
        STATUS OFF
        OFFSITE 255 255 255
        CLASS
                NAME "ASubject"
        END
END

I'm using the windows binaries for 4.2
Thanks,
C

Craig -

I'm not quite sure I exactly understand the symptom.  Does the error
happen when the layer has valid images but none of them are currently in
view, or when you view a layer with no images defined in it?  If it's
the first case, can you create the problem by scrolling/panning off the
edge of the data until it appears, and then pan back on to the map
correctly?

Folks,
I have several layers using TileIndexes which link to georeferenced tif
images. The layers show happily (when in zoom range) when one of the
images is displayed on the map image being requested but mapserver fails
with the following error message if there is no tile being displayed on
the reqeusted map image:

msDrawMap(): Image handling error. Failed to draw layer named 'Blah' 

I'm probably doing something quite stupid, but can anyone suggest what?
