Hi,

I'm having trouble using GeoWebCache with Mobile Atlas Creator (MOAC),
and I wonder what the soution is.

MOAC requires WMS source to be in EPSG:4326, see here:
http://sourceforge.net/apps/mediawiki/mobac/index.php?title=Custom_XML_Map_Sources#Custom_WMS_map_sources

But it seems that GeoWebCache is not good at working with EPSG:4326?
When trying to access a cached tile layer via the explicit GeoWebCache
URL of http://openaviationmap.tyrell.hu/geoserver/gwc/service/wms , I
get skewed images, and I get the following on the geoserver console:

12 Nov 06:36:21 ERROR [geowebcache.GeoWebCacheDispatcher] - X,Y values for the 
tile index were calculated to be {69.0, 47.31338231970476}  which had to be 
rounded to {69, 47}  and exceeds the threshold of 10%. Perhaps the client is 
using the wrong origin ? http://localhost:8088/geoserver/gwc/service/wms


now, if I go to the same layer 'straight', via the URL of say:
http://openaviationmap.tyrell.hu/geoserver/OAM/wms , I get the expected
results in Mobile Atlas Creator.

I tried this with 'simple' layers, and also with layer groups, and the
results are the same.


the reason I 'need' GWC for this is that it provides functionality I
need. it renders bigger tiles, and cuts them up later - this means that
labels are rendered differently (I'd call them: properly) this way.

Is there a way to have this issue solved somehow?

or, is there a way to extract seeded tiles from GWC in a say, 'known'
format?
