How to bind an element in an arrayList to a table column

Question

Hi everyone, I need your help.
I have an ObjectListDataProvider to bind a class MyClass to a table. Inside of MyClass, there is a property called dynNumOfElements of type ArrayList. I need dynamically create the columns of the table to match the number of elements in ArrayList, and bind each element in the ArrayList to a column.
However I dont know how to do it? It is going to be something like createValueBinding("#{currentRow.value(['dynNumOfElements[1]']}"). Obviously this does not work.
Can you tell me a way to solve this problem?
Is it possible to bind a column to an element in a collection?
Thanks in advance

Thanks Winston,
Following is what I did. They are all in Page1.jsp
public String getMyData(){
// Make sure to check for nulls
return myList.get(count++).toString();
private ArrayList myList = new ArrayList();
private int count = 0;
public String button3_action() {
// TODO: Replace with your code
//initialize list
myList.add("string 1");
myList.add("Stirng 2");
myList.add("string 3");
TableColumn tc1 = new TableColumn();
tc1.setId("tc1");
tc1.setHeaderText("tc1");
tableRowGroup2.getChildren().add(tc1);
StaticText st1 = new StaticText();
st1.setValueBinding("text", getApplication().createValueBinding("#{Page1.myData}"));
tc1.getChildren().add(st1);
return null;
The error message is "Error getting property 'getMyData' from bean of type helloweb.Page1"
Can you help me to fix the problem? Thanks a lot.
