My Env:
Microsoft Windows 7 Ultimate, 6.1.7601 Service Pack 1 Build 7601

Compass 0.12.2 (Alnilam)
Sencha Cmd v3.0.0.190
ext-4.1.1a



After generating my app, the 'model' and 'store' directories are missing / not created.

Here is the output from generate app:

And, here are the (I think) relevent directory listings:

(I use http://unxutils.sourceforge.net/, hence the ls command stuff)
