Scaffold issues in Rails 1.2

Hi all,

after generating a scaffold for a model I get an almost empty _form.rhtml:

<%= error_messages_for 'backup' %>

<!--[form:backup]--> <!--[eoform:backup]-->

however, the rest of actions (show and list) work fine. Is this new in 1.2 version? I don't mind to put the fields by myself but I was used to get filled up forms...
