Mark,
what you return is an arry of arrays of Strings.

But your outer loop has to return Beans (objects with getters, not arrays)
and you can then use the inner bean for another loop.


class App
{
  public B[] getBees()
}

class B
{
  public String getName()
  public C[] getCees()
}

class C
{
 public String getName()
}

---JSP:
<USEBEAN  name="appBean" type="App">
</usebean>

<LOOP PROPERTY="appBean.bees" PROPERTYELEMENT="beeBean">
        <display property="beeBean:name">
        <loop property="beeBean:cees" propertyelement="ceeBeen">
                <dislay property="ceeBean:name">
        </loop>
</LOOP>
---
it works OO!
