getPrintHTML returns null when called on a layout?

[jason.saunders]

I have the following test code;

isc.VLayout.create({
  ID: "layout1",
  members: [
    isc.Label.create({
      ID: "label",
      contents: "test"
    })
  ]
});

isc.Button.create({
  top: 100,
  title: "label print HTML",
  click: function() {
    alert( label.getPrintHTML() ); // displays the label print HTML.
  }
});

isc.Button.create({
  top: 150,
  title: "layout print HTML",
  click: function() {
    alert( layout1.getPrintHTML() ); // displays null.
  }
});

When I click the "label Print HTML" it shows the label print HTML.

But if I click the "layout print HTML" which calls getPrintHTML against a layout containing the label it shows null.

Am I doing something wrong?

Any ideas any one?

Pass a callback into getPrintHTML(), rather than gathering it's return value.

Great thanks. That works.
