<p class="">From time to time we get walkbacks on our
production servers when users want to login/create a
new session due to failed cleanup/unregister of old
sessions.</p>
<p class="">Here's an excerpt from the walkback (VA
Smalltalk):</p>
<p class=""><tt class="">MessageNotUnderstood
class(Exception class)>>#signalWith:</tt><tt
class=""><br class="">
</tt><tt class=""> receiver = MessageNotUnderstood</tt><tt
class=""><br class="">
</tt><tt class=""> arg1 = (nil Message
(#unregisterAt:, ('PZv9N5QPtkzYQMvH')))</tt><tt
class=""><br class="">
</tt><tt class="">UndefinedObject(Object)>>#doesNotUnderstand:</tt><tt
class=""><br class="">
</tt><tt class=""> receiver = nil</tt><tt class=""><br
class="">
</tt><tt class=""> arg1 = Message (#unregisterAt:,
('PZv9N5QPtkzYQMvH'))</tt><tt class=""><br class="">
</tt><tt class="">KontolinoSession(WASession)>>#unregister</tt><tt
class=""><br class="">
</tt><tt class=""> receiver = a KontolinoSession</tt><tt
class=""><br class="">
</tt><tt class="">KontolinoSession>>#unregister</tt><tt
class=""><br class="">
</tt><tt class=""> receiver = a KontolinoSession</tt><br
class="">
</p>
<p class="">Looking at WASession>>#unregister it
is clear that the variable @parent isNil and therefor
unregister cannot work. <br class="">
</p>
<p class="">Now I am wondering</p>
<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="">
</li>
</ul>
<p class=""><br class="">
</p>
<p class="">Any hints, ideas, requests for more details
are welcome.</p>
