<DIV></DIV>Actually I was able to get near to that, but thank you very much,
it cleared my mind. My problem still is to group things. So I
have a list of products and I want to group them by type. So I want to
create N lists for N types, each list with every product of a
certain
type.<BR> <BR>e.g<BR> <BR>Product<BR>-type<BR>-name<BR>-id<BR> <BR>=======<BR> <BR>productList{product1,
product2, product3,...,productN}<BR> <BR>I want a rule that
<BR> <BR>rule"group by type"<BR>
when<BR> iterate the List and generate a
productListbyType grouping all products of typeN<BR>
then<BR>
deliveryList.add(productListbyType)<BR> remove
each product from the main List(i dont think i really nedd
that)<BR>end<BR> <BR>and loop in that rule until list is 'cleared'(all
products have been sent to their right lists.<BR> <BR>sorry for bothering
you, but i really searched for that and did not found. I could iterate the
list with the from collect bu i dont know how to use an "abstract" type, how
to iterate for all kind of types. we can have N types.<BR> <BR>thank you
very much.<BR>

<DIV></DIV>alright. I was trying not to boder you.<BR> <BR>My
companie is developing a billing software for a e-commerce site. So we
have an Order and we have to transform it into deliveries. So each
Order has many products and I have to filter it and define X deliveries(i
call it 'delivery split'). There are filters like disponibility(in how
many days it will be ok), brach(in what city is the product), type(if it
is a kit, ticket...),...<BR> <BR>I tried many ways and i really
think that drools isn't the best tool for my problem. The point is that mi
boos dont want to use the hard code for define the deliveries. He
wats drolls to do everything. So i tried inserting the the order in the
WM, and using 'rom' chained with 'collect' i could iterate and set a list
based in some rules, but how can i create lists based on the branch. how
can i group in Y different lists the Z different products i
have.<BR> <BR>I also inserted each product manually and tried to
manipulate each one. But the point is that the rules should be
interdependent but i was not able to do it.<BR> <BR>the resume is
that i want to take the order and set N deliveries based on interdependent
rules. i would like to do almost everything with drools not using the hard
code.<BR> <BR>Sorry for the English, thanj you very much for the
help, i'm a little lost.<BR><BR>ect: FW: Can I use drools to solve my
