Re: [geomesa-users] Exception in storing null Point for geometry

Hi Suresh,

Currently we don't allow null geometries - this provides query consistency, as otherwise you may get inconsistent results depending on the specific index being used.

Thanks,

Emilio

Hello Everyone

I am using `Point` geometry type in geomesa for strong lat-long details in feature type. In one of the use case while storing a new feature I don't have value for lat-long so I tried sending `null` object for `createPoint` function, but the library 'jts' throwing exception while processing null Geometry type. [Here][1] is the source code. By seeing the implementation of `jts`library, It seems difficult for storing null in geomesa Point. It seems function createUuid needs an empty check for the Point.

Here is the snapshot of my code:

    sf.setAttribute(Attributes.GEOMETRY.getValue(), JTSFactoryFinder.getGeometryFactory().createPoint((Coordinate)null/*new Coordinate(event.lat, event.lng)*/));

Attaching logs for exception:

java.lang.IllegalStateException: getX called on empty Point
