"cannot bind or add elements because the node has no valid parent"

Question

Hello All,
  I keep getting the above error message. Can someone help ?
<u><b>Context Structure</b></u>
- A (Model Node)
- B (Sub Model Node of A)
   ++ Country (Model Attribute B)
   ++ Language(Model Attribute B)
<u><b>Coding</b></u>
IPrivateMainView.IAElement userInfo = wdContext.createAElement(new A());
wdContext.nodeB().addElement(userInfo);
The error stack always report that the above syntax causes the error message.
Can someone kindly let me know where I may have gone wrong ? Thank you.

Hi,
The model node is a reference to the model object so you need to bind the node to a similar structure or table from the model object.
eg.
abc(model node)
|__def(model subnode)
   |___attr_a
   |___attr_b
Then you need to first bind abc node
abc ele=new abc();
wdContext.nodeAbc().bind(ele);
Then bind the def to the corresponding def node
def subele=new def();
ele.setDef(subele); or ele.addDef(subele);
