comparing fact property to global causes NPE if global is set after the fact but before fireAllRules ---------------------------------------------------------------------------------------------------- Key: JBRULES-1827 URL: https://jira.jboss.org/jira/browse/JBRULES-1827 Project: JBoss Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-core Affects Versions: 4.0.7 Environment: Vista Reporter: David Hill Assignee: Mark Proctor This will cause an NPE prior to firing any rules, the NPE will occur at the workingMemory,insert statement. The workaround is to set the global before adding the Score fact. Java code: workingMemory.insert(new Score(1.23)); //has public Double named myScore initialized in constructor workingMemory.setGlobal("highPoint", 0.5); Drools code: global Double highPoint; rule "bootstrap1" when $s : Score(myScore > highPoint); then System.out.println("bootstrap1"); end -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
