Re: [rules-users] storing array in variable!
I believe that this happens because of the usage of x.y.z (nested
accessors). When using nested accessors, I think the engine is assuming the
result is a single object and not an array.
Can you please open a jira for it and attach a test case?
I will fix that for 4.0.2.
Thanks.

Hello Mr Edson,
I tried using memberOf , but i get
java.lang.ClassCastException: Can't check if an attribute is member of an
object of class class [Ljava.lang.String;
here is my code
MyFact($arraystore : x.y.z)
MyAnotherFact(a memberOf $arraystore)
where z is an string of array
and MyAnotherFact.a is a string
waiting for ur reply
thank you

Yes, but use memberOf instead of in:

when

AnotherFact( attr memberOf $array )

Re: [rules-users] parsing error using accumulate
Well, seems the parser is raising the wrong message here... need to fix that... But the syntax should be something like: rule calculate average when $media : Number( doubleValue 5) from accumulate( Instance( $value : classValue ), average($value)) then System.out.println(media ); end []s Edson 2007/9/6, Isabelle Hupont [EMAIL PROTECTED]: Hi!

Re: [rules-users] Still can't create a standalone application
That still hasn't fixed it. I can now compile it with javac without errors but it still gives noclassdeffound error when it runs. At least I now have your example that does work, so I am going to modify it bit by bit until I find out where my mistake is. My initial one was created with the wizard in eclipse so I'm not sure what has happened! Anyway, I will persevere and post the results in case anyone else needs pointers. Thanks all. Mark. Mark Proctor wrote: MarkA wrote: Okay, many thanks for this. Firstly, I apologise if I am asking these questions in the wrong place, I don't want to waste people's time but it is *very* frustrating for new users when problems like this occur. I scoured the documentation, the quick-start guide, the faqs and searched on the internet but could find no help. From some of the responses I have received from the various sources it seems that I am not the only person hitting these issues. Secondly, it looks like my error is that I set the CLASSPATH to point at the directories, .../JAR and .../JAR/lib, not each individual .jar file as in your batch file. I had tried it with just the small set of .jars that you have and, as far as I can tell, the only difference is using the directories in the CLASSPATH variable. I'll change that in mine and see what happens but I can compile and run the example you sent which is fantastic. This is standard Java, I don't think this is something we should be explaining, as it's done in hundreds of places around the net. Many thanks again and sorry for being stupid. np, stupid Qs are allowed (we get lots of them), but you have to expect a bit ot stick with them - call it character building ;) Good luck.

[rules-users] Deploying BRMS package
Hello, After building a rules package in BRMS, there is an option to create a 'Snapshot' and/or 'Download binary package'. If you select download, where do you put the .pkg file? How do you deploy the .pkg file and get your application to access it? The documentation does not say where to download the file to or how to use it. Could someone tell me.
