I am using wicket 1.1.1, but this error was there also with version 1.1.

includes a border component to define a layout. When I access the page
everything goes fine, but If I reload the page, the following error
occurs:

Re: [Wicket-user] Unexpected RuntimeException

2006-02-01 Thread Juergen Donnerstag
There is something wrong with your wicket:head tags. There must just
be one in each panel/border markup file. They are not allowed in
Pages. Without any more details it'll be difficult to help. Header
support is still fairly new and some parts are still under review.
Under the hood a lot has changed in 1.2 and I'd suggest you try 1.2
for better header support.
