I opened an issue (that is way old in principle). The problem is illustrated in a test (patch) and it has earlier been acknowledged to be a bug. I would like to here some comments on it on: https://github.com/rails/rails/issues/7247 Thanks in advance. jarl -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
