Bad condition operator "===" (triple equals) in room fire example ----------------------------------------------------------------- Key: JBRULES-2609 URL: https://jira.jboss.org/browse/JBRULES-2609 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-docs-expert Affects Versions: 5.1.0.FINAL Environment: environment not relevant Reporter: Julien Kronegg Assignee: Mark Proctor Priority: Trivial Context: The "Quick Start" chapter/"The Basics" section uses an example of fire in rooms. Issue: In one of the rule example snippet, the condition operator used is "===" (triple equals) instead of "==" (double equals): rule "Status output when things are ok" when not Alarm() not Sprinkler( on === true ) then System.out.println( "Everything is ok" ); end Location: In version 5.1.0.FINAL and also in trunk/rev34481 in the following file: http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-docs/dro... : line 389 Priority: Since this is in the basics, beginners read that chapter, so the priority could be higher than "trivial" -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
