Reasons: {1}", commandBase.getActionType(), StringUtils.join(returnValue.getCanDoActionMessages(), ',')); } // Set the correlation-id on the command commandBase.setCorrelationId(commandBase.getParameters().getCorrelationId()); return returnValue; } _______________________________________________ Devel mailing list Devel(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/devel _______________________________________________ Devel mailing list Devel(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/devel
