How to save a spatial dataset

Hello,
I installed ckanext-spatial. It works with geospatial-view if I upload a geojson. But spatial-query doesn't works. If I create a new dataset extra data is not saved. All data is in the geojson resource file. Solr extra field is created.
So how I have to save a dataset? (Lack of: e.g. "extras": {
"ext_bbox": "-7.535093,49.208494,3.890688,57.372349")

Regards,
Michael

Start by reproducing dataset creation with a GeoJSON resource and compare it with the working geospatial-view path. Inspect how spatial-query reads the Solr extra field and how dataset extras are saved. Done means the ext_bbox extra is persisted for a newly created dataset and spatial-query can use it.
