Re: [rules-users] Re: Inserting Facts within Action nodes (RuleFlow)
I would like to introduce if\while statements into the action node The use of if/while statements in the MVEL dialect is disabled, as it usually leads to less declarative rules. For simple if-statements, you can still use (x == null ? x : y). More complex if/while constructs can usually be defined more declaratively using extra conditions in the lhs of a rule. I must admit that in the context of action nodes, it might be valuable to enable them again in this context. But our latest code on the svn repository already extended the action node so that you can use the java dialect as well, without limitations. For now, I would suggest using rules to express you actions in complex cases, as they offer more flexibility. And expect to see some usability improvements to most of the ruleflow nodes in the future, as the 4.0.x part was still more like a proof-of-concept implementation for some of the node types.

I followed the instructions on the wiki page below and copied the 2 jar
files to server/default/lib. I then tried both 4.0.3 and 4.0.1 BRMS
.war files but got different errors for each. They are below.

[rules-users] Does BRMS run on Jboss 4.0.1sp1 AS
Hi, Does anyone know if any version of the Drools BRMS will work on the Jboss 4.0.1sp1 AS? I have been trying unsucessfully to get it to work. Fernando helped me some by suggesting I install the jsf dependencies on my app server. That fixed one problem. Another problem was fixed by removing 'cglib-full-2.0.1.jar' from the server/default/deploy/jboss-hibernate.deployer directory. Following those two changes, the BRMS now opens in the web browser but when I go to 'Packages' and try to add a new rule or create and save a new package, it dies again with these errors.

When using the 4.0.3 .war file, I get completely different errors and it dies before starting. Can you even use BRMS on anything earlier than 4.0.2 AS? If so, what else can I try to get around these errors? Thanks, Rod ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] Checking fact id
Hi guys, Now I am strugglin' with fact id checking or whatever we can call it :D Let's take into account the followong scenario: I have class A (it's just a name) javabeans to be inserted into the WM. I define two objects of class A: A1 and A2. Somewhere I do insert(A1) and insert(A2) ( let's say I do it in the same package of R1 and R2..see below...) Then I define two different rules R1 and R2 that reason over class A facts (let's say R1 and R2 are in the same package) . The point is I want R1 to fire only on A1 and R2 only on A2. Is that possible in drools? Is there a sort of fact id I can reason over? I do not think globals will be of any help, cause in the guide i have read that globals should never be used within LHS. We should never reason over globals. Let me know. Massi ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
