Hi,

since I’ve upgraded [rubyfrance.org](http://rubyfrance.org) with radiant 0.6.1 I can’t edit &  
save a  
text, because of this bug :

Frederic,

Did you run rake db:migrate when upgrading? 0.6 added optimistic  
locking to pages, and it looks like the field responsible for that is  
nil in your POST. It might fail if that column does not exist in the  
database.

That’s right, it seems that the default value 0 in the lock\_version  
field  
was not set when I had migrated db…  
Now it works better, thanks.
