Betto,
I just went down this road with ForEach in DroolsFlow. The documentation on
those properties was a little lacking in my opinion.
CollectionExpression = should be an expression that resolves to a
java.util.Collection. So a Person has a List<Loans>, and your flow has a
variable person which you set, the expression could be:
person.loans
VariableName = is the name given to the current item you are passing in.
Perhaps just loan. That is the variable that will be passed into your subflow
(or RuleGroup in your case.)
I did a similar thing with for a demo, but ran into another problem. I called
a Subflow from within the ForEach, and passed in my variable (lets say loan.)
I could access the variable easily enough in Actions, using code - like
loan.getStatus().equals("Approved")
but have not been able to get a RULE to execute against that variable. Like
$loan : Loan (status == "Approved")
Not sure what the problem was with my code, but will revisit later.
I bring that up in case you run into it because you are just calling a rule
within your ForEach. Maybe try a simple code action first, something like
System.out.println(loan.getStatus());
Anyway, let me know how it goes. Kind of nice to see someone going down the
same road...
Bill
