Macro dialogs with many pages: How do I edit them?

Hi

I have a situation under LibreOffice 3.5.6 with a dialog that has several steps. In the LibreOffice IDE, I see only the last page of the dialog.

The module that invokes the dialog uses the property Step as

oDialog.Model.Step = 1 ’ (…2,…3, or whatever page number)

How do I edit the dialog pages in the IDE? . Is there a trick to see all the dialog pages? If not, how do I change them?

Thank you
