Sorry, in looking over my other code I had called publish_display_data twice but thought it was only once. So, I haven't found a bug.<br><br><div class="gmail_quote">On Wed, Jun 13, 2012 at 6:56 PM, MinRK <span dir="ltr"><<a href="mailto:benjaminrk@gmail.com" target="_blank">benjaminrk@gmail.com</a>></span> wrote:<br>

The idea being "I have a thing I want to display, and I can display in all these different ways". It is up to the frontends to pick their favorite (HTML in the notebook). If you want to display multiple things, then you should use multiple calls.</div>
