Hi,
uncomment
//tileOrigin:origin.transform(proj4326,MAP_PROJECTION),
//tileFullExtent:bounds.transform(proj4326,MAP_PROJECTION),
then it should work. The service use the same values as EPSG:900913 in
OpenLayers.

Betreff: Re: [OpenLayers-Users] OpenLayers and GeoWebCache on GeoServer
Hi Tobias,
thank you for your hints. But i cannot get it running.
I think my problem has to do with the origin and size of my gwc-data,but i
cannot grab it where to start.
So my gwc-configuration(layer iis:Luftbilder) is on
http://tc.agroconnect.fh-bingen.de/geoserver211/gwc/service/wmts?REQUEST=get
capabilities
I have setup da demo under http://lw.igreen.fh-bingen.de/igg/olc.html
My errors (see firebug-console):
<ExceptionReport version="1.1.0"
xsi:schemaLocation="http://www.opengis.net/ows/1.1
http://geowebcache.org/schema/ows/1.1.0/owsExceptionReport.xsd"><Exception
exceptionCode="TileOutOfRange"
locator="TILECOLUMN"><ExceptionText>Column 0 is out of range, min: 8
max:8</ExceptionText></Exception></ExceptionReport>
Any ideas?
TIA Carsten
