I open a page with a GET parameter f.e. "view.jsf?id=1". In the backing bean I read the id variable in the @PostConstruct function and find the corresponding value object. All this works fine. But if I rerender the content where the backing bean is used, the GET parameter is no more available. I know, this is just working as designed. But how can I get passed the id to the backing bean when I rerender the content?
