How to access group content, or anything inside?

Question

Let's say I have this group:
var myGroup = Group{
     var someNumber:Number;
        var stf = SwingTextField{
             columns: 10,
              text: "TextField",
             editable: true
     content:[
          Text{
               x: 100;
               y: 100;
               content: someNumber;
               fill: Color.BLACK
                stf
}And let's say sometime when the program is running, the user changes the value of the SwingTextField. How do I access that? Like, I insert a rectangle inside the scene in the stage, and when the user moves the mouse it prints the content of the SwingTextField? And how do I access the variable "someNumber" as well? I tried things like println(myGroup.someNumber) or even println(myGroup) but nothing. Eclipse says it can't find "someNumber".
Thanks. JavaFX is a lot trickier than what it made me thought at first. It doesn't help that the tutorials I've read taught some bad habits.
_EDIT:_
I figured out myGroup.content[], but it doesn't let me access the attributes of the node, like when I use
myGroup.content[1].textIt can't find "text" even though it's already pointing to the SwingTextField (verified when I printed myGroup.content[1]), but the JavaFX documentation says it should have a text attribute.

If you look at the javafx doc for Group you will see that content is declated as a Node[] (a sequence of Node instances) which means each node included within will show up as a Node. It is up to you to cast it to its real type afterwards.
Alternatively, instead of direct access by index, you could set a unique id to each nodes and seach the content for a particular id. You will still need to cast afterward.
