[jboss-jira] [JBoss JIRA] Commented: (JBRULES-2518) equal sign (=) in string literal in MVEL modify statement causes error

equal sign (=) in string literal in MVEL modify statement causes error ---------------------------------------------------------------------- Key: JBRULES-2518 URL: https://jira.jboss.org/browse/JBRULES-2518 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-core (expert) Affects Versions: 5.0.1.FINAL Environment: Mac OS X 10.6.3, Java 1.6 Reporter: Steve Miner Assignee: Mark Proctor rule "mvel equal sign bug" dialect "mvel" when $d: Dog(name == "Bertie") then modify ($d) {name = "Bertie = Boy"}; end Note the string literal for the new value for name contains an equal sign (=). That causes an error. Apparently, the modify macro or the MVEL parser is choking on the equal sign. java.lang.Error: org.drools.rule.InvalidRulePackage: Unable to build expression for 'consequence': [Error: unterminated literal] [Near : {... h ($d) {name = "Bertie = Boy"} ....}] ^ [Line: 1, Column: 43] ' modify ($d) {name = "Bertie = Boy"}; ' : [Rule name='mvel equal sign bug'] If I remove the "=" from inside the string literal (substituting "is a"), it works as expected. rule "mvel equal sign bug" dialect "mvel" when $d: Dog(name == "Bertie") then modify ($d) {name = "Bertie is a Boy"}; end
