Hi all, 

i'm trying to use Rich Text Field on a Salesforce site's page with a custom controller. 

I updated both the controller and Visualforce page version at 18.0 :

- the controller, after this save, works correctly 
- but when i try to saving the version of this visualforce page, the error will appear is: 
"Error: Invalid field Description__c for SObject Ospitalita__c" 
(Description__c is the Rich Text Field) 


For your info, if i insert this rich text field in a empty visualforce page, it works correctly. 
But i give the error in my site pages , which have the template tags (apex:composition and apex:insert) . 

Are "this tags" the problem? 

How can i fix it? 
I need apex:composition and apex:insert and i don't want to delete them or substitute with component.

Thanks in advance!!
