In the sectioned marked "Documentation" there is the Drools manual. Its
s work in progress. But I took time to make rail road diagrams, similar
to BNF, for all valid syntax.

Can someone provide a summary of the new syntax? A BNF would be great. I
guess if it's just WHEN/THEN there's no need. I don't see any mention of this
on this on the http://drools.codehaus.org/ pages...

It is the Drools 3 lingo:
http://labs.jboss.com/jbossrules
It is just the new and improved way of writing if-then rules, but still
without the else!

What is this lingo that you guys are using, the when/then etc.? Is this
supported by Drools? Everyone just pushed back on me saying they're not going
to support the ELSE construct and here you are talking about a WHEN? I'm
confused. Please explain to a novice :)
Thank you.

I'm a neophyte at this as well, but I think I'd assert all the elements of
the list into WM.
Then the rule would just be:
rule
when
Element()
then
doSomething();
end
Or, if you need to only trigger something when the item is added to the list,
assert the list as a fact:
rule
when
$e : Element()
ActionableElements(elements contains $e)
then
doSomething();
end
Hello eliane,
Hello,
i'm trying to do the following with drools
Suppose we have an arrayList in our drl File and we want to compare
each
element in the list to a certain value if they 're equal then do
something
for each (element in List)
if (element == value)
doSomething()
else
next();
how can i utilize the while logic with drools?
