Hi, is it possible to use the for each loop in Drools?

Oh, do I need a loop xml definition? Good to know. -.- Could you give me a link with a good explanation/example about how to do this? Thanks :) Tina The for each loop in Drools Flow recieves a list of objects to iterate over it. Can you share your loop xml definition? and can you check that the variable that it's using is a list?

Probably I misread the question.. I thought that Tina was asking about for each loops in Drools Flow. If not where are you using for each?? A java for each each node in the RHS?

Yeah, I think using a normal for loop is better. I just came up with the question because I wanted to use a for-each-loop in a simple exercise-scenario, because it's a bit faster to write... Anyway, what I wanted to do is: for (Value value : $eventSet) { // raise hell } Thats where I get the type mismatch.
