After insert a customHandler I cannot be able to insert properties.

Appears

message

the extract of standalone.xml

<custom-handler name="MYHandler" class="loggerhelper.customLogHandler.MYLoggerHandler" module="loggerhelper.customLogHandler">

                <level name="ALL"/>

                <formatter>

                    <named-formatter name="MYPATTERN"/>

                </formatter>

                <properties>

                    <property name="fileName" value="${jboss.server.log.dir}/myLog.log"/>

                    <property name="maxSizeInMB" value="1"/>

                    <property name="maxBackupIndex" value="5"/>
