toggle "rendered" property by a4j:commandButton

Hi!

I am workign on a web shop application using Seam and RichFaces.

The shopping card is displayed inside a scrollableDataTable. Before integrating a4j I used a "outputText" control to show the text "shopping card is empty" instead of the empty table by setting rendered="#{not empty cart}" on the table.

Is there any way to rebuild this behaviour using a4j? (I want to show/hide the text and the table depending if the table is empty or not)

Thank you in advance!

use the same structure.. just update it properly after ajax actions. Conditionally rendered elements should not be updated directly via ajax - some parent should be updated to perform ajax show/hide. outputPanel is one of the right tags for such parent definition,.
