Is there a way to add a http parameter programatically in a seam component:
I tryed Parameters.instance().getRequestParameters().put(...)
but this is an UnModifiable Map..
My goal is to pass information from a parent conversation to a nested conversation (components are @PerNestedConversation so they don't share data each others...)
Can I add a parameter for the redirection without page.xml files ???
Request parameter's are set by the request - they aren't for output to the request. If you want to set parameters for a redirect, you'd need to modify the URL that was redirected to.
