I recently updated to rails 1.2.5 and I got gems installed for 1.1.0,  
1.1.6 1.2.0 and 1.2.5  
Since I wanted to revert my app back to 1.1.6 I set  
RAILS\_CONNECTION\_ADAPTERS = ‘1.1.6’ in enviroement.rb but that doesn’t  
seem to do the trick.  
Am I missing something?

you should set RAILS\_GEM\_VERSION to ‘1.1.6’ (or better freeze rails to  
the vendor/rails directory in your application)

Oh sorry, I copied the wrong text, I meant to write that I set  
RAILS\_GEM\_VERSION = ‘1.1.6’ in evinroement.rb…  
Thant doesnt seem to work properly.  
By the way, what do I need to do to freeze rails? Could you explain it  
clearly?  
Any guess at why setting RAILS\_GEM\_VERSION doesnt work?
