[JBoss JIRA] Created: (JBRULES-1046) Business Object returns null due to Shadow Fact, unless declared final

by Arjun Dhar (JIRA)

Business Object returns null due to Shadow Fact, unless declared final ---------------------------------------------------------------------- Key: JBRULES-1046 URL: http://jira.jboss.com/jira/browse/JBRULES-1046 Project: JBoss Rules Issue Type: Bug Security Level: Public (Everyone can see) Components: Reteoo Affects Versions: 4.0.0.GA, 4.0.0.MR3 Environment: Windows, X86 based machine Reporter: Arjun Dhar Assigned To: Mark Proctor SCENARIO ----------------- Define an Object 'BooleanConfiguration' public class BooleanConfiguration extends BusinessObject { String paramName; //with setter and getter Boolean value; //with setter and getter Client client; //with setter and getter -- Client is an object that composes of String clientId; } *BusinessObject is just a generic Object that maintains a reference to the Assertion List from where it came (Ref. to the container object, Collection). Action(s): ------------- 1. initialize the object with a Parameter and Value (Hard code to test) -- Set 2. Execute against a Rule: When config: BooleanConfiguration(value==true) Then //Do something end EXECUTION NOTES: ------------------------------- 1. I asserted this object and the rule was not executing as I expected. 2. I put a break point in the object, and found that it set it correctly but whenenver the rule engine called the get method the vaue of the object was null. 3. I traced this the place where it creates shadows in Rete.java. I had observed a similar behaviour in version 3.1 or 3.6 (if there was a 3.6). it was more prolific then. 4. I made the class 'final' (This prevents a shadow from being created), and voila my rule worked as expected. Note: None of the other objects needed a final, but had comeplex associations. But this particular object does not run, unless declared final. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
