[jboss-jira] [JBoss JIRA] Commented: (JBRULES-1826) illegal group reference while try to compile rule

[Edson Tirelli (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBRULES-1826?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12461350#action_12461350 ] 

Edson Tirelli commented on JBRULES-1826:
----------------------------------------

Did you tried to escape the {}? The new DSL parser is much more robust and strict. It interprets anything inside non escaped {} as a variable name.

Try the following:

[consequence][]log an error "{errorCode}"= String[] errorMessage = \{$name\}; errorlist.add( new UWError("{errorCode}",$driverKey, errorMessage) );
