<ul class="">
<li class="">how could @parent become nil? <br class="">
The only thing I can think of is a user clicking on
"logout" twice. The logs of our application,
however, don't support this thesis...<br class="">
</li>
<li class="">is this a (known and/or even fixed) bug
in Seaside or our code? We haven't implemented any
access to the @parent variable...<br class="">
</li>
<li class="">is it a good workaround to intrudoce a
notNil check in our WASession subclass' #unregister
method before sending super unregister? <br class="">
We will try this of course because it is not a good
marketing gag to greet users with an error screen
instead of a login form<br class="">
