[Opensource] checkbox dbobject attribute

[Maurizio Brilli]

Hi everybody!
I can't seem to find any doc about which attributes can be associated to 
a DBField, nor the meaning of the value to bind.
After a lot of browsing I found some discussion in the forum, but no 
details at all. Can anyone point me to the details of the implementation 
or provide some sample code? Mean, I saw the eForum Subscriptions 
DBObject, but it uses char(1) fields, while I'd like to use booleans.
Thanks in advance
Maurizio
