Multiple layer download fails

[ingenieroariel]

The multiple layer download fails with the following json response:

''"process":"id":1,"status":"FAILED","progress":0,"reasonForFailure":"java.lang.String cannot be cast to com.vividsolutions.jts.geom.Geometry"''

with the following geoserver log:

''ERROR [data.shapefile] - The following locker still has a lock read on file:''

The error appears only when trying to download postgis layers, when the shapefile has to be created in the "gs-data/process-tmp-dir/".

This specific bug is disappeared in the new versions. However another one related is opened.
The map/x/download is still not working.

After some bug hunting the problem seem to be that while creating a MapLayer the ows_url is set to DEFAULT_LAYER_SOURCE['url'] from the settings module but the MapLayer.local method compares the ows_url to the settings.GEOSERVER_BASE_URL address which is usually different. The result is that no MapLayer is considered as local and then the download fails.

Possible solution can be found here [https://github.com/simod/geonode/commit/4a999eb428196d492247038b1a0772bdd1b531d0]

However there can be different solutions.
Needs further discussion.

@ingenieroariel lets discuss this one and determine whether it still occurs and needs to be fixed. Seems like a pretty critical bug if it is still occuring.

Hi, I tested today against GeoNode 1.1.1 and the bug is still there. simod@4a999eb#L1R1552 this solved. But let's discuss this solution since I'm not sure is the best.

This might be related to gh-160

I verified this issue is fixed when building packages from today's master.
