[rules-users] Multiple independent Assertions
Hi, In stateless Session: If List of A1,B1,C1 are executed - execute(List) and at the same time in a paralell thread A2,B2,C2 are executed - execute(List) In Theory (Conceptually), I want to confirm if A1 will interfere with the rule using A2? Just want to ensure what is appropriate or expecteed behavior. ...assuming both threads hit the same session for that delta t period of time. thanks, arjun ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] Multiple independent Assertions
shadow proxies protect you a little from this, but you can still end up with garbage. What a shadow proxy does is copy all the fields, so that during insertion time anychange to the original data will not impact what th network sees.

Re: [rules-users] Does Drools 4.0 rules have downward compatibility with lower versions.?
Hi , I just found the below statements from the documentation As mentioned before Drools 4.0 is a major update over the previous Drools 3.0.x series. Unfortunatelly, in order to achieve the goals set for this release, some backward compatibility issues were introduced, as discussed in the maiil list and blogs. Where can i get more information on the backward compatibility issues ?

[rules-users] correlating two collects
I am finally having some time to use collects. What I basically need to do is to collect items from a list using a specific criteria, then collect items from a diff list using another criteria, and finally compare the groups collected using a 3rd criteria Here is what I am thinking: i : Item(type==A) ig : ItemGroup(size1) collect Item(a==i.a, b==i.b, ... n==i.n) i2: Item(type==B) ig2 : ItemGroup( size1, ga==ig.ga, gb==i.gb, ) collect Item(a==i.a, b==i.b, ... n==i.n) 1) It is quite nice that any implementation of java.util.Collection can be the resut of collect. ItemGroup here not only keeps hold of all Items returned but has some aggregate properties (afaik, I cannot use the aggregate functions with accumulate since I have multiple column aggregation). 2) Am I on the right track? Or is there a better way? 3) Is the collect recomputed from scratch or incrementally every time a new fact is asserted or updated? thanks ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

So let me confirm. Question) I hvae a rule When obj: MyComposedObject(active == false) Then //Action End .. the problem is, if the above object was never asserted; I still want it to execute. Luckily MyComposedObject is composend inside another object, so can i use the technique above as When obj: Composer( this not contains MyComposedObject) End or even obj: Composer( this not in MyComposedObject) ... My Composer simply composes the object and does not contain it in a list. Q1) So would either or both not contains or not in work?

Q3) Stretching my actual use case to its limits; if I want to write conditions over objects that were never asserted into the working memory (need to OR them with existing) ones, how do I do that? I understand technically it does not make sense to want conditions over objects one never asserted; ... but please think a moment. A person asserts Objects and due to some external factor some objects do not get asserted. Since he is aware of it, can he trap that conidtion in the rule itself?
