[Tobago] Howto display a popup with a button

[H. Swaczinna]

Hi,

I would like to display a popup panel on a button click. I tried this:

        <tc:button label="Popup">
          <f:facet name="popup">
            <tc:popup>
              <tc:button label="Ok"/>
            </tc:popup>
          </f:facet>
        </tc:button>

But it didn't work. There are only examples with a popup on a toolbar
and I can't find any hint howto use a popup with a button. Isn't it
possible at all?

Regards
Helmut
