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

    The XFA object model is divided into a number of parts, the form is under xfa.form, the template under xfa.template, etc.  To use the descendent operator, the two dots ".." you have to say which model to look in.

    Try

    xfa.resolveNode("xfa.form..ChildSubform").MyTextfield.rawValue

    or

    using the shortcut

    xfa.resolveNode("$form..ChildSubform").MyTextfield.rawValue

    I think there is no form object in yout form named „xfa“, isn't it? I this way the result „null“ is correct.

    The correct script should propably be:

    this.resolveNode("ChildSubform.MyTextfield").rawValue

    Here's a very good explaination of how the resolveNode() and resolveNodes() methods work: resolveNode vs. resolveNodes

      thanks for your answer, but xfa is the topmost node in xml based forms by default
