Thanks.
I tried surrounding the form with a panelGroup and rerendering that. The UI behaved correctly but I got the same warning as before:
Aug 20, 2007 8:28:07 AM org.apache.myfaces.trinidadinternal.io.DebugResponseWriter _logDuplicateId
WARNING: The id "org.ajax4jsf.view.state" is used more than once.
I also tried surrounding the form with a div and that did not work. The UI did not rerender properly and I got the following in the console:
Aug 20, 2007 8:31:32 AM org.ajax4jsf.framework.ajax.AjaxContext convertId
WARNING: Target component for id parent not found
Any other suggestions before I abandon trying to get Trinidad and Ajax4Jsf to work for this case?
