Problem creating dynamic component children with RestoreState of JSF 1.2

Question

Hello everybody,
With JSF 1.1, it was possible to create children of a component dynamically in the constructor of a component.
But now, with JSF 1.2, there is an issue with the RestoreState as a new instance of each component of the tree is created.
Does someone has an idea on how to solve this issue?
One possibility is to create the children not in the component, but in the renderer of the component.
But I'm not really convinced of this solution...
Thank you in advance.

You can create a new component dynamically in the method setParent() according to the following code snippet:
public void setParent(UIComponent parent) {
if (parent != null) {
List<UIComponent> children = parent.getChildren();
Application application = FacesContext.getCurrentInstance().getApplication();
     componentLabel = (HtmlOutputLabel) application
     .createComponent(HtmlOutputLabel.COMPONENT_TYPE);
     componentLabel.setTransient(true);
     children.add(componentLabel);
     } else if (parent == null) {
     if (componentLabel != null) {
     List<UIComponent> children = getParent().getChildren();
          children.remove(componentLabel);
          super.setParent(parent);
     }
