Grails log4j configuration - ERROR Method missing when configuring log4j: logger

Question

For what ever reason when I attempt to add a logger {...} block to my Grails log4j configuration, I receive the following error:

log4j:ERROR Method missing when configuring log4j: logger

Can anyone see what might be wrong with my configuration? This is a Grails 1.3.3 application (soon to be upgraded to 2).

TIA,

John

log4j = {
   error 'org.codehaus.groovy.grails.web.servlet',  //  controllers
         'org.codehaus.groovy.grails.web.pages', //  GSP
         'net.sf.ehcache.hibernate'
   debug 'org.hibernate'

   appenders {
       console name:'stdout', layout:pattern(conversionPattern: '[%t] %-5p %c{2} %x - %m%n')
   }

   logger {
      grails="error"
   }

   root {
      info 'stdout'
   }
} 

I also get the following error just beforehand and don't know if it could be related?

You're mixing up your syntaxes - logging configuration changed completely between Grails 1.0 and 1.1. Instead of

logger {
  grails="error"
} 

you just need

error 'grails'

along the same pattern as the debug 'org.hibernate' you have higher up.
