[GeoNode-users] Issues with mosaics in GeoNode

Thanks for your help. I've solved the issue. Probably I've messed up gdal
(a long story...). WIth a fresh installation everything is fine. Anyway,
I've used the datastore.properties file as suggested and it works
About the cache. I believe the _invalidate_geowebcache_layer method is
called not only when the style is updated (which is fine) but probably
every time the metadata is updated (which can cause some headache if you
work with large datasets).
