JSP/JSTL parsing ArrayList that is property of passed object

I am trying to sort through a tricky JSTL problem, hoping to get some help with...

I am passing a table object from Spring MVC controller to a JSP using ModelAndView, the table object has an ArrayList of Row objects, which in turn each have an ArrayList of Field objects.

I am populating the Table object in the controller for display on the jsp page, and I am trying to figure out how to parse through the Arraylists to produce an html table using JSTL.

So as a starting point, looking at the Table object...

Using Spring 3.0 MVC

Model:

public class Table {

private String id;
private ArrayList<Row> rows;

public String getId() {
    return id;
}

public ArrayList<Row> getRows() {
    return rows;
}

public void setRows(ArrayList<Row> rows) {
    this.rows = rows;
}

Controller:

Table table = new Table();
ArrayList<Row> rows = new ArrayList<Row>();
ArrayList<Field> fields = new ArrayList<Field>();

fields.add(new Field("0","test0"));
fields.add(new Field("1","test1"));
fields.add(new Field("2","test2"));

Row row = new Row();
row.setPKValue("testPK");
row.setFields(fields);
rows.add(row);

table.setRows(rows);
table.setId("test");

ModelAndView mav = new ModelAndView();
mav.addObject("table",table);
mav.setViewName("healthcenter/report");

return mav;

JSP File:

<c:forEach var="row" items="${table.rows}">
${row.PKValue}
</c:forEach>

This doesn't produce any output, I was expecting the row PKValue property to be output, not sure where the problem is, any insight would be great!

Assuming the method on Row is getPKValue, then you need to refer to it in the JSP as pKValue, not PKValue, i.e.

${row.pKValue}

It's a poor name for the property, though, it looks confusing. I suggest renaming it to something more conventional, e.g. getId (i.e. ${row.id}) or getKey (i.e. ${row.key}).
