Hi
We were ready to put a new wicket application into production, but after
deploying it it on our pre-production server with Weblogic 8.1 SP5+JRockit,
we see a really strange and serious problem.
Initially after deployment, everything works fine, but after refreshing
a page with a DataTable 10-50 times, the toolbar components added to the
DataTable
(column headers and the paging) disapears! And they disapear on ALL pages
using the DataTable component.
No errors in any logs, and otherwise everything works perfect.
Only re-deploying or restaring the server will make the toolbars come back.
Then we tried to download and deploy the Wicket-examples-1.2.5.war, and it
also fails in the same way,
after refreshing the "DataTable Example"
a number of times. Since it is configured as development mode, it does show
an exception instead of the toolbars jst disapering.
The exception is below, and indicate that the markup has "lost" it
references to the toolbars.
We can recreate the problem running WL+JRockit locally from IntelliJ, but
not when a debugger is attached (probably because optimization is then
turned off).
The strange thing is that only the toolbar components fail, and that it
fails only after showing such a page a number of times.
Also when one page with a DataTable has failed, all the pages in the
application using DataTable component will be in error
Since we are otherwise ready to go into poduction, we really need a
workaround or a fix,
but changing the application server or JVM will be really difficult because
we are a big company with standardized production servers.
I will be really really thankfull, if someone can solve this problem!

Unexpected RuntimeException
WicketMessage: The component(s) below failed to render. A common problem is
that you have added a component in code but forgot to reference it in the
markup (thus the component will never be rendered).
1. [MarkupContainer [Component id = 1, page =
wicket.examples.repeater.DataTablePage, path =
98:table:bottomToolbars:1.WebMarkupContainer, isVisible = true, isVersioned
