rich:tabPanel does not work with textarea-Collection of common programming errors

I think i got a bug of richFaces.

I have a simple page with a tabPanel with switchType=’ajax’ and 2 (empty) tabs, the first tab only contains a textarea whose value is bound to a bean property and the tabPanel just does not work. Becoming following log messages while trying to change the tab:

info [11:31:56.919]: Received 'begin' event from 
info [11:31:56.953]: Received 'beforedomupdate' event from 
info [11:31:56.957]: Element error
