Rails 1.1 - model access from view broken


I have a problem when refreshing a view that accesses a model method.
The method call works on the first iterration, but on subsequent page
refreshes, it generates an “undefined method” exception. The method call
is programatic (ie, it’s not an accessor). For some reason, it ends up
in ActiveRecord::Base#method_missing, which seems to be intended for
attribute accessors.

Anyone experience anything similar?
