Have you tried looking at afflnetworks\_controller.rb around line 5, the error message suggests there is a problem there. It is difficult to help without more information. 2009/4/22 PNDUR [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---

Thanks for your reply Colin Yes, I did. Line 5 reads is @afflnetworks = Afflnetworks… The default scaffold commmand generated line 5 as under. In both cases I get the same above error def index @afflnetworks = Afflnetworks.all ``` respond_to do |format| format.html # index.html.erb format.xml { render :xml => @afflnetworks } end ``` end I changed it to as follows. def index @afflnetworks = Afflnetworks.find(:all) ``` respond_to do |format| format.html # index.html.erb format.xml { render :xml => @afflnetworks } end ``` end ---

The same thing also happens when I call any method in the controllers and all the controllers. Think it is more than just that one line of code.
