Hi, I am very thankful for you answer.
Let me answer you points: Yes, it's the same machine and I use the same server: webrick. You second point: Before my post, I copied the configurations from the test environment to development environment and then I've got no problems. As you mentioned, the config.action_controller.perform_caching ist the problem. If it is set to false, I face the problems described. But development with config.action_controller.perform_caching set to true does not reload the source code after a new request, so I have to restart the server every time I make changes to the source. Last night, I tried to get some more information about the problem: as I mentioned, the error appears, when I do the second request in the webbrowser. The first access is always successful. I put out the ".methods()" list of the model instance and there I could see, that my own methods are not listed. Also the access methods of the association proxies seem not to be existent anymore. Then I tried the following: I extracted my methods and put them into a module. I included this module and suddenly those methods I extracted were existent again, also after a few reloads. But still, the association proxy methods are missing. I can't explain this to me. Do you have another idea? Thank you very much. ms --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
