Re: [rules-users] ClassCastException on session.insert(object)

We are using all the dependencies that is distributed with the binary release for 4.0.1. The problem also occurs intermittently so I think we can rule out dependency problems? I figured so much... I will probably have to get more information the problem I have is that this problem has only been encountered when the application is deployed to the application server. There is no stacktrace attached to the ClassCastException which makes debugging more difficult. Together with the fact that we are using an older Eclipse IDE which does not support the Drools-tools. BTW do anybody have any tips on debugging rules? I suppose I should RTFM, unfortunately it is a lot to consume at once.

Thanks for the help.

We are putting out 4.0.3 on monday, I would recommend you upgrade to this and make sure you are using all the correct dependencies. If you continue to have problems you will need to be more explicit than you have been below, there is't much we can do with that information.
