What do you mean with "the parent menu are no longer available" ?
With "getRequestCycle().scheduleRequestHandlerAfterCurrent(new
ResourceRequestHandler(byteArrayResource, null));" you tell Wicket to
stream the byteArrayResource to the browser.
If you use "Content-Disposition: ATTACHEMENT" then the browser will show a
dialog asking the user whether to save the file or to open it with the
default software (e.g. Adobe Actobat).
If you use "Content-Disposition: INLINE" then the browser will try to show
the file by using a plugin, i.e. open the .pdf in the browser if possible.
In both cases the parent component should not be affected. Either the page
is at its old state (ATTACHMENT) or completely replaced (INLINE).
