Essentially, the difference between the rules is that expression in the first rule is being converted into an MVEL expression, because of the nested accessors, while the second is a pure drools expression.

[rules-users] collect return random order
Folks, When using collect on List of items with some filter (criteria), I need to have result in the same order as it was received: F.e. I have a list of suppliers : List() : Supplier(FIRST, Status.ACTIVE), Supplier(SECOND, Status.INACTIVE), Supplier(THIRD, Status.INACTIVE) And I need to find first INACTIVE supplier, so it must be SECOND supplier. So doing the following : When $l : List() // list of suppliers $inactive_supp : ArrayList() from collect Supplier(status == Status.INACTIVE) from $l Then System.out.println($l); // prints FIRST, SECOND, THIRD System.out.println($inactive_supp); // prints THIRD, SECOND Instead of SECOND , THIRD So I am getting THIRD supplier instead of SECOND as the result.. Please advise if it is a bug .., or there is another way of doing that...

Re: [rules-users] Functionality/Performance Test Results
Hi, Robert, I am very interested in the database access part, because I am also considering to add the database access code into my rule. But my current concern is the performance. It would be very appreciated if can let me know how many times of database access is in your whole test suite, which cost 6 seconds? Is it always validating the same user or randomly picking different users to validate -- if using the same query, database may get result cached which will result a better performance? Did you add any arbitrary object caching in your java code for performance optimization? Thanks in advance, Yang On 8/24/07, Robert Crawford [EMAIL PROTECTED] wrote: Our users are asking to be able to specify custom validations in our application. I've been undecided whether to use a rules engine or write our own dynamic validation code. While it's admittedly still in the toy problem stage, I tried using drools in place of some existing hand-coded validation. The drools version took the SAME amount of time. Then I added another rule, to simulate the types of validations our users want to add, and re-ran. Again, SAME time. Admittedly, database access was the big time consumer -- average of 6 seconds per unit of work, and about 15 units of work per test -- but it was the same for both the rules-based and hand-coded validations. Excellent work, everyone!

Re: [rules-users] Storing temp results in eval block
Not really and that is why it is better to avoid eval() blocks. Can you show what rule are you trying to create? Maybe there is another way of writing it?

RE: [rules-users] collect return random order
Yang, I am was suggesting to have regulation to impose particular order(although it might be a good additional feature as well). Would like to just to keep the order as it was in collect list. Especially if we are returning List that means it is an ordered collection by definition. It looks like somewhere in the internals of collect there is a HashSet, sitead of ArrayList used that changes the order of the items in the incoming list, and that is what I don't agree with... I think it must be a bug, -Sergey From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Yang Song Sent: Monday, August 27, 2007 11:28 AM To: Rules Users List Subject: Re: [rules-users] collect return random order I saw someone is requesting LIMIT, here I saw Manukyan is asking for ORDER BY, and also Mark is talking the FROM. Looks like the rule LHS part would become more and more like SQL SELECT statement. :) I think it is the right way. Some Stream Database also extends the SQL to do event aggregation and correlation. The same can be applied to Rule Engine too.
