Dynamic datatable and command link

Question

I'm having a problem creating CommandLink's automatically. What we have is a tag, which can contain a set of data. We need this on several locations, so we have to create a datatable dynamically. When you press a link, it should be possible to retrieve the ID of the component on that specific row.
The problem is, we can create the table with the necessary data. When I construct the column with the ID (and the link), it fails.
Code:
HtmlCommandLink link = new HtmlCommandLink();
Application app = FacesContext.getCurrentInstance().getApplication();
ELContext elContext = FacesContext.getCurrentInstance().getELContext();
ValueExpression ve = app.getExpressionFactory().createValueExpression(elContext,"${" + TABLE_VAR_NAME + "." + property + "}", Object.class);
link.setValueExpression("value", ve);
link.getAttributes().put("rowId", ve.getExpressionString() );
link.addActionListener(
    new ActionListener(){
     public void processAction(ActionEvent arg0)
          throws AbortProcessingException {
          LOG.info(">>>>>>>>>>>>> Linked pushed !!"  +
          arg0.getComponent().getAttributes().get("rowId"));
selectColumn.getChildren().add(link);
datatable.getChildren().add(selectColumn);The rowId is always #{row.code}, instead of the actual data. Is there a way to create a command link dynamically, press it and retrieve the ID of that field? That expression should be evaluated at runtime and added to the datatable, but that doesn't happen apparently.

Answer 1

I've read your article, but I didn't find anything I could use. Facing a deadline and don't really have time to try out multiple (possible) solutions. The problem is that all the examples I can find point to MethodBinding, but I don't need that. I just need to get the ID of the row that was clicked, nothing more.
This works fine:
link.setValueExpression("value", ve);I don't see why the other expression isn't evaluated.
I can do getParent().getParent() to get a reference to the DataTable, but the datamodel on that object is empty btw.
