Re: problem with jumpstart protecting pages code

[John]

Bingo! You are right, @Persist was missing from my login page nextPageLink 
member. I'm not much a fan of putting data in session and probably ignored or 
junked that essential @Persist!

thanks,
John

  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.

  Geoff
