The problem is that $eventSet is a List<Object> and not List<Value>.
So you need to cast and use the old for loop:
for(int i=0; i <  $eventSet.size();i++){
    Value value = (Value)$eventSet.get(i);
}

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.


Thanks :)

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?

I'm not sure whether you and Salboy are on the same wavelength. Tina, please do provide more
details where and what you want to for-each-loop. Guessing is a waste of time...

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?

Hi,

The engine grouses a type mismatch : cannot convert from element type
Object to Value

Thanks :)
