I use two different request parameters to have bookmarkable URLs for a product or for a product group.
When I was still manually picking up the values from the request parameter map it used to work fine, except that after login redirection the request parameters were lost.
I followed suggestion here on the forum to use page parameters instead:
<param name="productGroupId"/> <param name="productId"/>
Now I had the much more severe problem that the parameters were always present and survived each request, so after I first selected a product I wasn't able anymore to select a product group instead.
I tried Contexts.getPageContext().remove(
productId), but that had absolutely no effect.
A workaround I learned while browsing source code and debugging:
FacesContext. getCurrentInstance().getViewRoot().getAttributes().remove("org.jboss.seam.PAGE$" + requestParamName);
Bug or by design?
(BTW I don't really understand why redirect.captureCurrentView can't simply capture request parameters, also.)
