[ckan-dev] problem with spatial previews

hi sol,

i solved the issue by activating the view in the frontend - maybe the docu
is not quiet clear :-( .
i thought, that the default view will sufficient - but
ckan.views.default_views setting don't activate the views for the resource
automatically :-( - i had to activate it in the frontend for each view - is
this realistic?
another problem is, that the wms preview don't work as it should do. the
layers are directly requested with the url of the that is defined in the
resource. this is not right. first the GetCapabilities request has to be
done and the GetMap url has to be extracted. with this url the map can be
invoked correctly. i 've done a adoption for the code two years ago. maybe
i find it and can give it back to the list.

also simple wfs are not supported - i tested
http://mapserver.lgb-rlp.de/cgi-bin/erdbeben?&request=GetCapabilities&VERSION=1.1.0&SERVICE=WFS

i also tested kml and geojson preview with follwoning urls:

http://www.geoportal.rlp.de/mapbender/php/mod_GetPublishedData.php?wmc_id=13986&outputFormat=geojson
http://www.geoportal.rlp.de/mapbender/php/mod_GetPublishedData.php?wmc_id=13986&outputFormat=kml

but the resource is not shown on the map :-( - maybe s.o. knows the problem.

thanx in advance,
armin
