Erubis / Rails Question

I’m trying to figure out whether the fix for an error I get when using Erubis belongs to Erubis or Rails so I can submit a bug/patch/whatever. When you use form_for in an Erubis template the instance_eval uses _erbout instead of _buf. I found the solution [adding ActionView::
Base.erb_variable = “_buf” to the setup in app/controllers/application.rb] but in searching out information about this I discovered that there was a recent Edge Rails patch to use _buf instead of _erbout. I’m thinking it just needs to be reported to the Erubis people and add the simple line to the directions. Anyone think otherwise, that this is a Rails issue as well?

Thanks in advance,

RSL
