But the problem doesn't appear if I test in local with webrick (in development or production environment) but it appears with apache+mongrel. All the libraries are in the same version on both configuration (1.1.6 for rails, 1.3.0 for transaction-simple and 1.1.3 for pdf-writer). I really don't know what to do. Any help ? Thanks in advance. ++ Jerome
