Panel.getComponent(int) returns Component, not String.

Typically, you do the following when attempting to 
manipulate the nested components of a panel:

  Component [] components = myPanel.getComponents();
  for ( int i = 0; i < components.length; i++ ) {
    if ( components[i] instanceof JTextField ) {
      ((JTextField)components[i]).setText(...);
    }
  }

I don't know what you mean by it not being in the "property string."
Furthermore, unless you set the component's name when instantiating
it, it will have no name.  That is, you have to explicity  write:

  JTextField newTF = new JTextField();
  newTF.setName("tf001");

in order to name a component.  The name you give a variable
is not the same as the component's name.
Following the approach outlined above to access the components
nested in a panel, you would write (assuming you did name the
components when dynamically adding them):

  String name = "";
  Component [] components = myPanel.getComponents();
  for ( int i = 0; i < components.length; i++ ) {
    if ( components[i] instanceof JTextField ) {
      name = components[i]).getName();

      if ( name.equals("tf001") ) 
        ; // do something
      else if ( name.equals(...) ) 
        ; // and so on
    }
  }
