UndefinedException when working with RL-facts and testing at design time

Question

Hi,
I'm performing some tests with JDeveloper Rules Designer on a very basic level. I'm defining rl facts (fact types), define a rule and write a test function to test this rule at design time. When executing my test function with the "Test Function" function an error occurs:
UndefinedException: symbol 'Person' is undefined in main...
Person is a fact type (RL Fact) that is the output parameter type of the decision function. If I don't use an output parameter everything works fine.
If I use XML Facts instead of RL Facts and define an output parameter for the decision function everything works fine, too.
Are there any restrictions for rl facts?

Sure you can read and write at the same time. But normally you would be reading from one place and writing to another place.
I rather regret avoiding the OP's earlier post asking how to combine two classes. I looked at the two classes posted and realized the best thing to do was actually to break them into more classes. But I also realized it was going to be a big job explaining why and how, and I just don't have the patience for that sort of thing.
So now we have a Big Ball Of Tar™ and I feel partly responsible.
