No longer null, now empty string...
In converting some more of the code from JSF Beta to JSF 1.0 I ran into another gotcha. Previously if I had form fields with nothing in them they would leave the values of the managed beans null. In the 1.0 release they set the values to the empty string (i.e. value.length() == 0). No big deal but my example would not work anymore because it relied on null's.
