hi all,

I have edge installed and try to use acts\_as\_tree. Since it is now a  
plugin I installed it. It installed successfully but I get an  
undefined method `acts\_as\_tree’ error.

In my modelcode I have  
acts\_as\_tree :order =\> “name”

Do I somehow have to add something before this code to make sure it  
looks for the acts\_as\_tree in the plugin folder?

Thanks  
Stijn
