Hi John,
It works because LoginPage persists the link in your session:
@Persist
private Link nextPageLink;
Have you really seen it fail? Try for yourself - try user 2 (login with admin,
admin):
http://jumpstart.doublenegative.com.au/jumpstart/theapp/security/userview/2
then log out, then try user 3:
http://jumpstart.doublenegative.com.au/jumpstart/theapp/security/userview/3
then log out, then try role 1:
http://jumpstart.doublenegative.com.au/jumpstart/theapp/security/roleview/1
Does it ever not work? If it needs fixing then I'd really like to know.
