So... I just tried the following and it worked, so I guess I answered
my own question. Sorry for troubling you folks.
private Object deleteItem( long id, String page, String context ) {
itemDao.delete( id );
Component comp = componentSource.getPage( page );
if( comp instanceof FlashMessagePage ) {
((FlashMessagePage)comp).setFlashMessage( "Bah Humbug!" );
}
return context != null
? pageLinkSource.createPageRenderLinkWithContext( page, context )
: pageLinkSource.createPageRenderLink( page )
;
}
Btw, it's not at all intuitive that this would work. I guess what's
happening is that when you acquire a page instance and set (persisted)
values on it, then those are the values that will be used the next
time the page is accessed?
