Problem with seting action method to a Hyperlink object

Question

Hi there,
as the subject says, I have a problem wih setting the action method of a Hyperlink object. Here is how the program is organized:
I have an external bean which generates an ArrayList of Hyperlink objects. In the backing bean of my web page I call a method from the above mentioned external bean to generate the list of hyperlink objects. After that in the page bean I insert the hyperlink objects in GridPanel component. So far everything works fine, but the action method of the Hyperlink objects is not called and I can't understant why.
Here is how I add the objects to the GridPanel component:
private void populateGridPanel()
        Hyperlink hyper;
        for(int i=0; i< checkboxList.size(); i++)
                hyper = (Hyperlink) hyperlinkList.get(i);
                vehicleGridPanel.getChildren().add(hyper);
    }All properties of the Hyperlink objects are set in the external bean not in the page bean, here is how:
//action method executed when the hyperlink is clicked
MethodBinding mb = (MethodBinding) FacesContext.getCurrentInstance().getApplication().createMethodBinding("#{Page1.hyperlink_action}", null);
veHyperlink.setAction(mb);The populateGridPanel() method is called in the init() method of the page bean, after the initialization of all other components.
An interesting fact is that if I manually drag-n-drop a hyperlink object to my page and programatically set its action method with the code above everything works fine. But using the same code for the dynamically generated hyperlink objects inserted in the grid panel doesn't work.
Any kind of help is highly appreciated.
Thanks!

I got this use case to work as follows:
1. Drag a Grid Panel and set its columns property to 1.
2. Drag a Message Group.
3. Use the following code in Page1:
public void prerender() {
populateGridPanel();
private void populateGridPanel() {
if (gridPanel1.getChildren().size() > 0) {return;}
for (int i = 0; i < 3; i++) {
Hyperlink veHyperlink = new Hyperlink();
//action method executed when the hyperlink is clicked
MethodBinding mb = (MethodBinding) FacesContext.getCurrentInstance().getApplication().createMethodBinding("#{Page1.hyperlink_action}", null);
veHyperlink.setAction(mb);
veHyperlink.setText("dynamic hyperlink " + i);
veHyperlink.setId("dynamicHyperlink" + i);
gridPanel1.getChildren().add(veHyperlink);
public void hyperlink_action() {
info("Yup it worked at: " + new java.util.Date());
4. Fix imports, Run, and then click on the hyperlinks.
