Hi ,

we are facing a serious problem at a customer's production site, which makes
it hard for us to debug. We are getting a ClassCastException in setupForRequest at


            _propertySource = (IPropertySource)
servletContext.getAttribute(name);

I do not have any good ideas but I recognize the situation (non-tapestry app). In our case the web application was unloaded, replaced with a new version and then re-deployed. Since weblogic was running the whole time the JVM was never interrupted. This caused problems with our property classes. They were static singletons so they were not unloaded when the web application was unloaded. However, the new version of the application changed the property classes. This meant that that the classloader considered the old live instances not the same class as the new versions. So, I guess that a question would be if your problems occurs on a newly started server or only when you have restarted an application?
