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.

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._______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
