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

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... <br>
<br>
Anyway, what I wanted to do is:<br>
<br>
for (Value value : $eventSet) {<br>
// raise hell<br>
}<br>
<br>
Thats where I get the type mismatch.<br>

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

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

Oh, do I need a loop xml definition? Good to know. -.-<br>
<br>
Could you give me a link with a good explanation/example about how to
do this?<br>
<br>
Thanks :)<br>

Can you share your loop xml definition? and can you check that the
variable that it's using is a list?<br>

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

Thanks :)<br>
