I tried with the 1.2beta1; same problem.  /Frank   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Johan Compagner Sent: Tuesday, March 07, 2006 7:44 AM To: wicket-user@lists.sourceforge.net Subject: Re: [Wicket-user] Rendering DataTable or DataView (or model) as Excel sheet   "MarkupContainer [Component id = 1, page = <No Page>, path =1.MyDataTable$1]]  " component id == 1, DataTable? It looks like a Item in the table that was removed. Which version do you use? Because there was an error that is recently fixed that sets the parents to the right values if a markupcontainer children did get rollbacked. Can you try with 1.2beta1? johan On 3/7/06, Frank Silbermann <[EMAIL PROTECTED]> wrote:     On 3/6/06, Frank Silbermann <[EMAIL PROTECTED]> wrote: From 2006/02/01: >> Of greater concern is that if I

why this happens. i can look into it if you reproduce it in a quickstart project. -Igor   I'm not sure what a quickstart project is.  Do you mean a zipped minimal web application that demonstrates the
