Building a model based on the OpenGIS KML with Google's kml extensions.
This requires 4 schema definitions that I have annotated for Ecore.
The (OpenGIS) Kml schema extends an AuthorLink schema and it also
extends a XAL schema. The (Google extensions) Kml22gx extends the Kml
schema.
All seem to work fine, except for the editor and adding children. I
would like to be able to see 'Children that Kml elements didn't know
existed (Kml22gx child) elements show up in new Child menus of the
editor for KML elements.
So in following the 'Creating Children You Didn't Know Existed' tip, I
set the genModel to 'Child Creation Extenders'=false & 'Extensible
Provider Factory'=true for XAL, AuthorLink, and Kml schemas and for
the Kml22gx I set 'Child Creation Extenders'=true & 'Extensible Provider
Factory'=false.
But when I try to generate the edit code for the kml22gx I get a NPE.

John,
I don't see anything obvious to explain the NPE...

Hi Ed,
Any suggestions how I could troubleshoot this? Would like to see what
this would look like in a debugger, but at a loss on how to do it.
thanks,

John,
Assuming you have the Eclipse SDK installed, if you started a new
Eclipse under debug control you could find the source for this line and
see that's going on. You could import your projects into that workspace
and reproduce the problem...
Cheers,
Ed
