Before I dig in any further (since I have no idea where to go from  
here…)

Has anyone been succcessful with 2.3.2, AS, and nested scaffolds?

I have the latest of AS and the render\_component plugin via  
% script/plugin install --force  
git://github.com/lackac/render\_component.git  
-r rails-edge

I have an AS user\_controller:

active\_scaffold :user do |config|  
…  
config.nested.add\_link(“Portfolios”,[:portfolios])  
end

But when I click on the Portfolios link I get:

ActionView::TemplateError (undefined method `format\_column’ for  
#ActionView::Base:0xb67cee38) on line #28 of vendor/plugins/  
active\_scaffold/frontends/default/views/\_nested.rhtml:

format\_column is defined in:  
…/vendor/plugins/active\_scaffold/lib/helpers/list\_column\_helpers.rb

which is included via:  
…/vendor/plugins/active\_scaffold/lib/helpers/view\_helpers.rb

which is included via:  
…/vendor/plugins/active\_scaffold/environment.rb

which is included via:  
…/vendor/plugins/active\_scaffold/init.rb

so I don’t understand why it’s not defined when needed.

Any pointers/ideas will be much appreciated. This worked fine in  
2.2.2.

Thanks,

Problem was that I had installed the newest AS on top of an earlier  
version, so …/frontend/default/views contained \*.html.erb and  
\*.rhtml files.

The latter ones were being picked up instead of the former.

I deleted AS and did a fresh install and all is good.
