Problem with binding sequences to attributes

Question

Hello everyone.
[you may directly jump to the question at the bottom of this post and if you don't understand what the heck I'm asking, feel free to read the whole post ;)]
I wanted to crate a table node where several attributes are for rows only.
Because i want it to be a CustomNode, the table should be created dynamically (one should at least be able to define different amounts of rows and columns at the initialization).
My problem is a combination of "creating dynamically" and binding attributes.
To create an arbitrary amount of rows i use a "while(i < x) CustomNode{}" loop.
To store the value of an attribute for a row i use sequences. So during the loop i do the following:
someValue: bind sequenceValue[i]
After quite some frustration i finally discovered that all the attributes will be bound to sequenceValue[last value of i].
I don't find the right words right now, so here's some code to demonstrate the problem:
package javafxtestbench;
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.text.Text;
import javafx.scene.text.Font;
import javafx.scene.CustomNode;
import javafx.scene.Node;
import javafx.scene.Group;
import javafx.scene.input.KeyEvent;
var t1 = [true, true, false];
Stage {
    title: "Application title"
    width: 250
    height: 500
    scene: Scene {
        content: [
            Text {
                font : Font {
                    size : 16
                x: 10
                y: 30
                content: "Application content"
            createFubar(),
function createFubar(): Group{
    var grp : Group = Group{
        content:[         
            //this works
            /*b1{ blob: bind t1[0]}
            b1{ blob: bind t1[1]}
            b1{ blob: bind t1[2]}*/
            //this doesnt
            createSomeBs(),
        onKeyPressed: function( e: KeyEvent ):Void {
            println("=== KeyPressed ===");
            if (t1[2] == true) t1[2] = false
            else t1[2] = true;
            println("new sequence value: {t1}");
    grp.requestFocus();
    return grp;
function createSomeBs(): Node[]{
    var i = 0;
    var grp : Node[];
    while(i < 3){
        insert b1{
            blob: bind t1[i]
        }into grp;
        i++;
    println("Sequence @ startup: {t1}");
    return grp;
class b1 extends CustomNode{
    public var blob = true on replace{
                println("attribute value b1.blob: {blob}");
    override function create():Node{
        Group{
}As you can see i created a CustomNode (b1) and use two different methods to add it to the scene.
First method: i add b1 thee times to the scene and set the attribute
or
2nd method: i use a loop (its index to bind the corresponding sequence entries to the attributes)
finally i added a key listener, which changes the value of the last sequence value if an arbitrary key has been hit.
output for using the "this works" block (1st method) after pressing some keys:
=== KeyPressed ===
attribute value b1.blob: true
new sequence value: truetruetrue  //contains {true, true, true}
=== KeyPressed ===
attribute value b1.blob: false
new sequence value: truetruefalse  //contains {true, true, false}and here for the "this doesnt" (2nd method) part:
=== KeyPressed ===
attribute value b1.blob: false
attribute value b1.blob: false
attribute value b1.blob: false
new sequence value: truetruetrueSo even though all elements in the sequence say "true", the attribute values of all CustomNodes will keep saying "false".
Here it's due to the fact that "i" is in the end greater than the sequence (cause by the increment at the end of the loop).
In the end all attributes will be bound to the same entry. So messing around with the index, so it doesn't get beyond the sequence size, won't help.
So to finally bring this post to an end ;P, here's my question:
How do you create an arbitrary amount of Nodes containing attributes which are bound to a list entries?

HI
  May be  you can fetch the data from the table with  looping the table size  and catching the
index of the elements .  To be more clear .
  1 . get the size of the table .
int leadSelection=  wdcontext.node<TableName>.getLeadSelection();
    for (int i=0 ;i<n;i++)
      if(wdcontext.node<tablename>.isMultiselected(leadSelection))
        String name = wdcontext.node<tablename>.getelementatindex(leadSelection).getname();
         similarly fetch the size of the other elements from the table .
    and set to other RFC as
        ZClass  abc = new ZClass();
         abc.setName(name);
wdcontext.node<NameName>.bind(abc);
and othere thing is when  you use Abstract class you can insert only one element at a time .
or may be you may want to set the values direclty to the RFC
       AbstractList  lst = new  ZClass.ZClassList();
       ZClass cls = new ZClass();
        clas.setName(name)
  lst.add(class);
wdcontext.currentRFcNameElement.modelObject.setName(lst);
and
execute the RFC .
