[ https://issues.jboss.org/browse/WFLY-1791?page=com.atlassian.jira.plugin.... ] Miguel Moquillon commented on WFLY-1791: ---------------------------------------- Hum ... I'm sorry but in Wildfly-9.0.2 this doesn't work when using levelRange expression, whatever the coma is or not escaped: write-attribute(name=filter-spec, value=levelRange["ERROR"\, "DEBUG"]) The error that is displayed: The batch failed with the following error (you are remaining in the batch editing mode to have a chance to correct the error): {"WFLYCTL0062: Composite operation failed and was rolled back. Steps that failed:" => {"Operation step-3" => "WFLYCTL0097: Wrong type for filter-spec. Expected [EXPRESSION, STRING] but was LIST"}} -- This message was sent by Atlassian JIRA (v6.4.11#64026)
