Question

If I have domain classes like:

class A {
 short aCode
 //...
 static hasMany = [bs : B]
 static mapping = {
   id column: 'a_code' name: 'aCode'
 }
}

class B {
  long bCode
  static belongsTo = [a: A]
  id column: 'b_code' name: 'bCode'
}

And try to use the B class in a command:

class SomeCommand {
  List<B> bs = ListUtils.lazyList( [], FactoryUtils.instantiateFactory(B) )
}

My input for aCode should be:

<input type='text' name='bs[0].a.aCode' />

Why this is not binded by grails controller? command.bs[0].a stays null after binding.

I’m using Grails 2.0.3

Answer 1

Actually the data binding with command objects and Lists does not work. There’s a JIRA for this.
