Dialog Programming, Opus II

Thanks to James Hassell, I have made significant progress in my dialog
programming.  However, I am not clear on what can and cannot be done
in a "heavyweight i-action," it being very much a trial and error
undertaking.  Once can change labels and hide/disable controls.  Using
James's example above once can populate lists in the PREINIT stage of
dialog creation.  What I would like to do is populate a second list
following user selection of a variable.  That list would be populated
with the results of a levelsof.  I have tried to extend James's
example with a second ado, but I don't seem to be able to change the
contents of a list class once the dialog box has been created.  Am I
correct in thinking that once a dialog box has been initialized that
the only changes that can be made are to the interaction with the
controls themselves, not to the *contents* of the controls?

I see a way around this by creating a new dialog box to create and do
the picking of levels.  This would be similar in function to the ifin
expression builder dialog.  Am I correct in assuming that this would
be a viable alternative?  Are there any caveats?

Many thanks.  Although I have thoroughly read the dialog and class
sections, it is not always obvious how to use them to accomplish
specific tasks.
