Unable to use [import] lu feature to include other Language Definition files using the Bot Framework Composer

[AlexBrownShi]

Can someone refer me to a working example that uses the [import] construct to include other LU files? I've spent quite a bit of time on this and I can't seem to get it to work.

My entities are auto-generated files from a data source, so I badly want to have a separate file for each entity and make references where needed. However, I'm having trouble getting this work. It WILL recognize the common.en-us.lu file that comes out of the box, but if I put entities there, they are not recognized. Other [import] references give errors.

Anybody have a working example?
