Hi Ron,

thanks for your answer!

| I don't fully understand what your ICallback does and where in the work 
| flow it is activated -

Well, actually as a first version I just took the one from the vlib example...
When the user has been idle for some period of time the login page is shown
again and he is able to re-login. After that the page he had visited
before the session became invalid is shown. But this only works for pages
where no database record has to be read in pageBeginRender() because the
database id (which is normally passed for example as a parameter with a
DirectLink) is unknown and an exception is thrown :(
 
| My solution is to design pages that always work, thus, keep the minimum 
| necessary in the Visit (eg current logged in user-id) - the rest on the 
| client -

And in your page classes (probably in a page superclass) you reload the
user object from the id every time a page gets loaded?

Sincerly,
  Andreas
