xfa.resolveNode("xfa..someNode").rawValue returns null

Hi

if have like this structure, where there is only one instance each:

ParentSubform

     ChildSubform

          MyTextfield.rawValue = 99999

now, i try to get that value in ParentSubform::initialize event:

var value = xfa.resolveNode("xfa..ChildSubform").MyTextfield.rawValue;

console.println("vlaue: " + value); // null

console.println("value: " + ChildSubform.MyTextfield.rawValue); // 99999

did I misunderstand the resolveNode function?

Thanks
