Hi, in AlphaNode.java (similarly beta nodes descendants) public void assertObject(final InternalFactHandle handle, final PropagationContext context, final InternalWorkingMemory workingMemory) throws FactException { if ( this.constraint.isAllowed( handle.getObject(), workingMemory, ... } // I need to put code here to get the rule and previous statisfied conditions } I need to get rule that owns the alpha or beta node as well as all the previous conditions that have been satisfied. For example: Rule 1 : Condition1 -> Node1 Condition2 -> Node2 Condition3 -> Node3 so if fact1 satisfies condition 1 & 2 only, but condition 3 doesn't satisfy it, I need to store the information that rule 1 with condition 1 & condition 2 have been satisfied. So , how can I get the rule that owns the condition? Can I get this information from workingMemoryEventSupport.fireObjectInserted event?

I would follow a different path. During network building you have that information. So, make the nodes reference their rules objects, or have a String[] for the rule names at least. Some considerations: * A node may be shared among multiple rules, so you will need a list of rule references for each node. * Be careful with memory consumption. Find a cheap way to store such information. * Make sure your schema does not increase serialization cost too much. At runtime, then you have the information ready to go in each node. What are you working on? Would you be willing to contribute back to the project?

Hi, I tried your guidelines, but I need to get the rule id (or object) and store it in the ObjectTypeNode , the problem I don't know from where to get this information as this is the stack trace till the ObjectTypeNode constructor. ObjectTypeNode.<init>(int, ObjectType, BuildContext) line: 96 PatternBuilder.attachAlphaNodes(BuildContext, BuildUtils, Pattern, List) line: 187 PatternBuilder.attachPattern(BuildContext, BuildUtils, Pattern) line: 88 PatternBuilder.build(BuildContext, BuildUtils, RuleConditionElement) line: 60 GroupElementBuilder$AndBuilder.build(BuildContext, BuildUtils, RuleConditionElement) line: 111 GroupElementBuilder.build(BuildContext, BuildUtils, RuleConditionElement) line: 69 ReteooRuleBuilder.addSubRule(BuildContext, GroupElement, Rule) line: 149 ReteooRuleBuilder.addRule(Rule, InternalRuleBase, ReteooBuilder$IdGenerator) line: 122 ReteooBuilder.addRule(Rule) line: 119 ReteooRuleBase.addRule(Rule) line: 266 Can you give me guidelines on how to get the rule object or rule name in the ObjectTypeNode constructor? Thanks.
