You can download the XSD here: http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-compiler/src/main/resources/META-INF/drools-processes-5.0.xsd And each node type and their attributes are explained in the docs: https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/t

[rules-users] Drools-flow: Event within foreach throws ClassCastException

Hello, i'm using the latest version 5.1.1 of drools-flow for a POC project. I have a process definition where I have an intermediate event node within a foreach CompositeNode. When I trigger the event using processInstance.signalEvent() I get a ClassCastException: java.lang.ClassCastException:

Please open a JIRA. If it is not creating a new fact type, i.e., only attaching metadata to existing types, it should either "merge" metadata or raise errors. Also, documentation was not updated in that place. Can you mention that please, as we need to fix as well. Explicit expiration polici

Re: [rules-users] [Drools Flow] checking Properties of supplied variables in constraints

Hi Kris, You were right - now it's working. i had just copied the rule-constraint from annother sample i was basing my app on. didn't know that a code constraint was existing. is there a more low level documentation available that describes Drools on XML level (what types/keywords are allowed)

Hello, I made a small test class result package com.sample; public class Result { private long resultId; public long getResultId() { return resultId; } public void setResultId(long resultId) { this.resultId = resultId; } public Result(long resultId) { super(); this.resultId = resultId; } } clas

Re: [rules-users] Same rules applies twice

If there are two Result() facts which aren't identical and you want to match only one in your rule you'll have to (a) provide a distinguishing restriction (b) use some information saying that the rule has already fired for a certain resultId. For the latter, you could use the Test fact. Not being

My technical id is a long. But if I just do an equals id does not chage the issue. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Same-rules-applies-twice-tp1861724p1861859.html Sent from the Drools - User mailing list archive at Nabble.com. __

In fact here I need the two results ... this is the result for the same computation ... but at different step. So they are attached to the same test. Here I want to create or reload and existing tests. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Same-r

Re: [rules-users] Same rules applies twice

Inserting two equal objects results in two facts, and each will trigger a matching rule. If your class Result contains a proper implementation of equals() and hashCode(), you may use KnowledgeBaseConfiguration conf = conf.setOption( AssertBehaviorOption.IDENTITY ); KnowledgeBase kbas

Re: [rules-users] Some Problem with drools-persistence-jpa Library

Thank you, Kris, this works well. But I think when using pi.signalEvent under persistence environment, a more reasonable exception other than NPE would better be used! This is really confused if I don't know the truth. 2010/11/8, Kris Verlaenen : > Hi, > > If you use persistence, you should use ks
