I have just tried to run my app under Rails 2 but I have hit a strange  
error message and wonder if anyone here can give me any pointers. The  
error is:

ActionView::TemplateError (undefined method `new’ for “rhtml”:String) in  
portal/index.rhtml

You can see the full error log here: [Parked at Loopia](http://pastie.caboo.se/154221)

This is on Instant Rails 2. My app works fine on Instant Rails 1.7 and  
in my Netbeans environment, buth using Rails 1.2. I wanted to get my  
code adjusted for Rails 2 before updating my Netbeans environment.

Thanks…

perhaps because in Rails 2.0 a view file x.rhtml needs to be renamed  
to x.html.erb ?

@John – Can you show us the controller method?

@Rick – No, 2.0 is backward compatible with the .rhtml files. I’ve  
got many rendering with no problem.

Hi, there is no code in the portal controller:

class PortalController \< ApplicationController

end

I will download the latest versions of the plugins that I am using. I  
currently have  
active\_scaffold (latest version downloaded today)  
acts\_as\_fulltextable  
attachment\_fu  
headliner  
settings  
styler  
markaby  
will\_paginate

The problem was with Markaby. This plugin seemed a great idea but looks  
like it isn’t actively maintained any more. I found a patch to the code  
here:

[http://dev.rubyonrails.org/attachment/ticket/10543/markaby\_fix.diff](http://dev.rubyonrails.org/attachment/ticket/10543/markaby_fix.diff)

This fixed it for me. Thanks guys for your responses 🙂
