[OpenLayers-Users] Unable to use both OpenLayers.Layer.Google and OpenLayers.Layer.TMS

[bdw]

Hi Tim,
Thanks for your reply.

I performed the following tests :-

1) Set OL to default EPSG (i.e. 4326), one non-cache wms base layer - worked
2) Set base layer to tilecache wms - worked
3) Set EPSG 54004 with one non-cache wms base layer - worked
4) Set base layer to tilecache wms - nothing displayed

Then I tried a single call to the tilecache like you suggested, the
following call :-

http://192.168.0.4:8081/?LAYERS=nzmap&FORMAT=image%2Fpng&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&SRS=EPSG%3A%2054004&BBOX=16280475.8648%2C-1300840.7104%2C17532820.136%2C-48496.4392&WIDTH=256&HEIGHT=256

returned :-

An error occurred: couldn't calculate tile index for layer nzmap from
([16280475.864800001, -1300840.7104, 17532820.136, -48496.439200000001])

I assume this index error means that the tolerance value like you mention is
at fault, I dont
have a good enough understanding of the internals as to why the EPSG:4326
works and
EPSG:54004 causes this tolerance error.

Was thinking it could be my geoserver setup as I added the 54004 SRS entry
but from watching the 
logs the requests never get that far and stop as you suggest (I believe) at
the tilecache.
