Hi Michael,

i have found strange behavior. All worked fine.
i change the one line in the config/model file 
from 

Category
    name Text

to

Category
    name Text Desc



After that all application was broke .  Seems like all 'exports' from Model.hs was lost.
If i change back to 'name Text'  all works fine again.

Thanks.
