Re: Inserting Facts within "Action nodes" (RuleFlow)

by Massi Gmail

Thank you very much Kris. I will define such a rule. thanks again. Now I am experiencing something different... I would like to introduce if\while statements into the action node "code part". Is that possible? Every time i introduce such a statement into the "textual editor "I get back a Mvel exception. In case It were not possible, I think I would use another rule like the one you suggested me. Grazie.

Currently, it only has access to global variables. It might indeed be a good idea to also allow access to some kind of workingMemory variable. We will try to add support for that when we add support for process variables. If you want, you could open a JIRA for this to track the issue. Your solution, defining wm as a global, seems a possible workaround (and I don't see any problems that might arise by doing this). Another one would be using a ruleset node instead of an actionNode, and specifying a rule that does not have any conditions, something like: rule "MyRule" ruleflow-group "MyAction" when then insert(new Object()); end Kris ----- Original Message ----- From: mmquelo massi To: Rules Users List Sent: Wednesday, January 02, 2008 7:55 PM Subject: [rules-users] Inserting Facts within "Action nodes" (RuleFlow) Hi guys, Is it possible to insert a new fact in the ruleflow action nodes?

Custom EvaluatorFactory

by Andy Mei

Hi, Is there a way I could register my own custom EvaluatorFactory? Drools ships with DateFactory what compares only dates, but no time is included. I would like to compare time as well. I see that it would be very helpful to include capability to register custom EvaluatorFactory. Thanks. Andy

Re: JUnit and classpath

by J Michael Dean

I noticed the absence of asm and tried to manually add version 3.1 and this had no effect on the trace. The MinimalDrools plugin is just my plugin to contain what I thought was the minimal amount of Drools stuff; I have the exact same error when I put everything that is in the Drools distribution in the classpath. - Mike On Jan 2, 2008, at 10:00 AM, rules-users-request(a)lists.jboss.org wrote: > > > Mike, > > So it seems you are missing the ASM jar in your … [View More]classpath... did > you tried > adding it? > BTW, what is this MinimalDroolCore_1.0.0.jar that you are adding to > your > classpath?

Inserting Facts within "Action nodes" (RuleFlow)

by mmquelo massi

Hi guys, Is it possible to insert a new fact in the ruleflow action nodes? I tried it simply adding an "insert(new Object())" instruction in the action-node "textual editor" but I got back the following exception: * org.mvel.PropertyAccessException*: unable to resolve property: insert(new Object()) Is it a simple dialect issue ? How to do it correctly? Thank You! Massi

Re: Inserting Facts within "Action nodes" (RuleFlow)

by Massi Gmail

I think i worked it around. Before I fired the rules, I put the following instruction in the "main" code: workingMemory.setGlobal("wm", workingMemory); Ofcourse in this way I can access the working memory within the ruleflow action nodes and I can use them in order to assert new facts into the "wm" global. Does it sound a bit tricky? Does it imply horrible integrity\security issues? Please, I need a feed back from the "drools" guys to know whether what I did is correct or not. Thank You … [View More]

Re: [rules-users] Flow of rules ?

by ekke

hi barath, both rules are valid, so both rules will be fired. the Rules engine decides which to run first. you have to use salience if you prefer one rule running first or you have to use a RuleFlow. ekke -- View this message in context: http://www.nabble.com/Flow-of-rules---tp14573971p14580184.html Sent from the drools - user mailing list archive at Nabble.com.

Qualifing objects on LHS

Re: JUnit and classpath

by J Michael Dean

Thanks. When I do that, there is no reference to org.objectweb.asm, nor is there even any reference to any asm library. The information is about 800 lines long and it clearly shows classes loading from my "minimal core Drools" plugin; when I add the entire Drools distribution to the classpath I get a similar dump with loading from the complete Drools distribution. I am attaching a text file with this information but I am guessing it will get stripped away by the server. I very … [View More]
