Grails log4j Appender not Working

Question

I use Grails 2.5.6 and I try to create 2 different appender.
The first appender should log all errors.
The second appender should log all infos.
I created the appenders but its still not working.
(The log files are created correctly)

log4j = {
    appenders{
        appender new DailyRollingFileAppender(
            name: 'errorLog',
            threshold: Level.ERROR,
            datePattern: "'-'yyyy-mm-dd",
            file: "logs/dev/${Metadata.current.'app.name'}##${Metadata.current.'app-version'}-error.log",
            layout: pattern(conversionPattern: '%d [%t] %-5p %c{2} %x - %m%n')
        )

        appender new DailyRollingFileAppender(
            name: 'infoLog',
            threshold: Level.INFO,
            datePattern: "'-'yyyy-mm-dd",
            file: "logs/dev/${Metadata.current.'app.name'}##${Metadata.current.'app-version'}.log",
            layout: pattern(conversionPattern: '%d [%t] %-5p %c{2} %x - %m%n')      
        )

    }

    root{
        error 'errorLog'
        info 'infoLog'
    }

    error  'org.codehaus.groovy.grails.web.servlet',  //  controllers
           'org.codehaus.groovy.grails.web.pages', //  GSP
           'org.codehaus.groovy.grails.web.sitemesh', //  layouts
           'org.codehaus.groovy.grails.web.mapping.filter', // URL mapping
           'org.codehaus.groovy.grails.web.mapping', // URL mapping
           'org.codehaus.groovy.grails.commons', // core / classloading
           'org.codehaus.groovy.grails.plugins', // plugins
           'org.codehaus.groovy.grails.orm.hibernate', // hibernate integration
           'org.springframework',
           'org.hibernate',
           'net.sf.ehcache.hibernate'
}

Thanks for help.

Not sure if this causes the problem, but I noticed two things in your example:

1. The file attribute in both appenders is the same

   file: "logs/dev/${Metadata.current.'app.name'}##${Metadata.current.'app-version'}-error.log",
   

2. The block for the log levels is missing (see enter link description here)

   log4j = {
       error  'org.codehaus.groovy.grails.web.servlet',  //  controllers
              'org.codehaus.groovy.grails.web.pages' //  GSP
   
       warn   'org.apache.catalina'
   }
