By taking the big dataset that I had originally in JML format and converting a 
subset of it with ogr2ogr into GeoJSON.  Test data contains 100 first features 
selected with SQL "limit 100 offset 0".  I believe that the error comes from 
the latter half because I can edit the schema of json file that I captured with 
"limit 50 offset 0".  I would look for gml_id=jarvi.106 which has NULL where 
other features have data.

Aihe: Re: [JPP-Devel] Can't edit the schema of some layers

how did you create it? manually by editing the geoJson file with a text editor?
