Description

class MainClass {
  List<MSID> MainList = [].withLazyDefault { return new MSID() } 
}

class MSID{
  List<Item> subList = [].withLazyDefault { return new Item() }	 
}

And in controller when I say

MainClass mainObj; 
.....
List<Item> listWithoutNullValues = mainObj.MainList.subList.grep()
for(Item provision : listWithoutNullValues){
  println provision.someValue
}

Cannot cast object 'groovy.lang.ListWithDefault@1d9e316' with class 'groovy.lang.ListWithDefault' to class 'com.abc.Item'
  due to: groovy.lang.GroovyRuntimeException: Could not find matching constructor
