I'm having a little problem with even a simple SessionState String object.
On one page I have this:
@SessionState
private String userColour;
...
userColour = "red";
Then on a subsequent page I have this:
@SessionState
private String userColour;
...
System.out.println("colour is " + userColour);
But instead of printing "red", the page throws the following error. It
looks to me like it is trying to recreate the String object from a fancy
constructor. But it isn't supposed to recreate the object, is it?
Isn't is supposed to store the object in memory just the way it is
without recreating it with a constructor?
An unexpected application exception has occurred.
