How to set List and Tree Binding Value manually from backing bean?

Question

Dear All,
I somehow found this code to work so that I could set a value on my bindings from a managed bean.
  public void setBindingExpressionValue(String expression, Object value)
    FacesContext facesContext = getFacesContext();
    Application app = facesContext.getApplication();
    ExpressionFactory elFactory = app.getExpressionFactory();
    ELContext elContext = facesContext.getELContext();
    ValueExpression valueExp =
      elFactory.createValueExpression(elContext, expression, Object.class);
    valueExp.setValue(elContext, value);
  public class MyBean{
  private String employeeId;
  public void inAmethod(){
       setBindingExpressionValue("#{bindings.employeeId.inputValue}",
                                     getEmployeeId());
  }Now, I am thinking. What if I have a List or Tree Binding in my managed bean then how or what should I send
to the expression value. Is it a List or Map?
The first one was easy as it is just a string but how about when dealing with collection?

Hi,
a tree binding does not set the value of the tree but determines the selected node. The binding itself represents the collection model that shows the hierarchical tree structure. So your question does not apply to a tree
