Re: [geomesa-users] NPE in geomesa:Density 
Jason, Emillio:

     Thanks for the replies.
So I have applied both changes. I am getting the same error with the same stack trace. 

I upgraded to GEOMESA 1.3.0 same issue.


My URL is now as follows:

http://52.222.65.14:8181/geoserver/wms?service=WMS&version=1.1.0&density=true&request=GetMap&layers=OE_Repository:OEEvents,OE_Repository:OEEvents&styles=heatmap,threat&bbox=31.6,44,37.4,47.75&width=1200&height=600&srs=EPSG:4326&format=application/openlayers&env=radiusPixels:30

If I change the styles to just use threat the query works.
If I change the heatmap style to user gs:Heatmap (versus geomesa:Density) it works. 

Below is my heatmap style:

Hi all:
I have a small (7 node) Accumulo 1.6.5 cluster with Geomesa 1.2.7.2 
installed.
I am using Geoserver 2.10.1.
I have installed the wps extension for geoserver, and followed all the steps 
I could find in the documentation.

I have my own ingest of GDELT data that has about 400K events in the
data store.
Normal point based WMS renderings work fine (really fine actually), WFS
queries
also work fine.

However, I am trying to use the heatmap.sld
I have added it to Geoserver. But any attempt to query my layers with it 
causes geoserver to throw a NullPointerException.

Attached is the stacktrace from my catalina.out

Any suggestion?
