When trying to serialize a Package I get the message that org.drools.base.dataproviders.MVELDataProvider is not serializable. I only get this problem when I have the "from" word inmy rules. Looking at the code is does seem that this class is not serializable, and also one of its including memebers.

I saw you already put the fix in, however I think that within the MvelDataProvider you have a "DroolsMVELFactory" which is also not serializable. I'm working with MR2 and fixed it there, I wanted to add it to MR3 but I see it has different code so I guess so other fixes were done there. BTW. On earlier versions of drools I only needed the drools-core jar in runtime. Now it seems I will also need to add the mvel jar as well. It was nice not having to care about such dependencies.

Hello, I downloaded the JBoss Rules 4.0 Eclipse IDE. I built a small project with about 120 rules. My test asserts around 500 objects. When I try to add one more rule (regardless of the content of the rule) I get the error below, stating no such method error. Even if I add the following rule, I still get the error: rule "new rule" when Object() then System.out.print("test"); end What other problems can throw these errors? Thanks, Steven -- Steven E.
