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 :)

E.g., Joshua Bloch, "Effective Java", Item 46: Prefer for-each loops to traditional for loops. Plain old Java.

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,

is it possible to use the for each loop in Drools?
The engine grouses a type mismatch : cannot convert from element type
Object to Value

Thanks :)
