you following:

class domain {     string lastname     string firstname     int age }  class command {     string lastname     int age }  def domain = new domain(lastname:'last', firstname:'first', age:33)  def command = new command() command.properties.findall{ !["metaclass","class"].contains(it.key)}.each { k,v ->    command[k] = domain[k] }  assert 33 == command.age assert 'last' == command.lastname     

the problem .properties includes 'class' , 'metaclass'. setting these 2 bad idea, they're getting filtered out.
