Problem with context binding

Question

Hi all,
I have the following problem with my context element.
I have this structure in my context:
DynamicText (valueNode)
  Person (valueAttribute)
  SourceRegistration (valueAttribute)
  Persons (valueNode in node DynamicText)
    Persons (valueAttribute in node Persons)
Now im trying to fill this context data in my code like this:
IPublicTESTComponent.IDynamicTextElement dynamicText = wdContext.createDynamicTextElement();
dynamicText.setSourceRegistration("sourceRegistration");
dynamicText.setPerson("person");
Collection personList = new ArrayList();
for (int i=0; i<4; i++) {
  IPersonsElement dynamicPerson = wdContext.createPersonsElement();
  dynamicPerson.setPersons("test person: " +i);
  personList.add(dynamicPerson);
wdContext.nodePersons().bind(personList);
wdContext.nodeDynamicText().bind(dynamicText);
On this code i receive the following fault message:
com.sap.tc.webdynpro.progmodel.context.ContextException: Node(TESTComponent.DynamicText.Persons): cannot bind or add elements because the node has no valid parent
How can I bind the persons on this context please?

Hi
The problem in the code I see DynamicText node must be supplied before Persons one because it's a parent node.
Binding the Persons node depends on property "singleton" setted on the node. If 'singleton'==false
wdContext.nodeDynamicText().bind(dynamicText);
wdContext.nodeDynamicText().getDynamicTextElementAt(0).nodePersons().bind(personList);
If 'singleton'==true ensure that 'initializeLeadSelection' property of DynamicText node is TRUE then use
wdContext.nodeDynamicText().bind(dynamicText);
wdContext.nodePersons().bind(personList);
