Hi,<div><br></div><div>Selecting a different look using Pier&#39;s PRDesignChooserWidget causes an WAUnregisteredHandlerError exception to be raised. This occurs on the latest builds: <a href="http://hudson.lukas-renggli.ch/job/Pier%202/lastBuild/">http://hudson.lukas-renggli.ch/job/Pier%202/lastBuild/</a></div>
<div><br></div><div>The PRDesignChooserWidget registers &#39;pier&#39; with the new structure in place then sends an #expiredKey response as:</div><div><br></div><div><div>    self requestContext responseGenerator</div><div>
        expiredKey;</div><div>        respond</div></div><meta charset="utf-8"><div><br></div><div>The problem appears to be in a change to WAResponseGenerator&gt;&gt;expiredKey, which was introduced:</div><div><br></div>

<div><br></div><div><a href="http://code.google.com/p/seaside/issues/detail?id=552">http://code.google.com/p/seaside/issues/detail?id=552</a></div><div><br></div><div>- Corrected WAResponseGenerator&gt;&gt;#expiredKey to always use the correct URL</div>
<div>- Implemented WAPathConsumer&gt;&gt;#upToEnd</div></div><div>----</div><div><br></div><div>The exception is thrown in the line:</div><div><div>url := self requestContext handler url.</div></div><div><br></div><div>#handler returns a WASession which I presume wasn&#39;t expected when the code was written.</div>
<div><br></div><div>Changing the code to:</div><div><br></div><div>url := self requestContext request url</div><div><br></div><div>stops the exception from being thrown, but doesn&#39;t result in a URL free from keys; not the desired effect. I found a handy Pier extension method WAUrl&gt;&gt;purgeSeasideFields.The rewritten WAResponseGenerator&gt;&gt;expiredKey then becomes:</div>
<div><br></div><div><div>expiredKey</div><div><span class="Apple-tab-span" style="white-space:pre">	</span>&quot;The session key has expired, redirect the request to the home directory preserving the path as well as possible.&quot;</div>
<div><br></div><div><span class="Apple-tab-span" style="white-space:pre">	</span>| url |</div><div><span class="Apple-tab-span" style="white-space:pre">	</span>self request isXmlHttpRequest</div><div><span class="Apple-tab-span" style="white-space:pre">		</span>ifTrue: [ ^ self forbidden ].</div>
<div><span class="Apple-tab-span" style="white-space:pre">	</span>url := self requestContext request url.</div><div><span class="Apple-tab-span" style="white-space:pre">	</span>url addAllToPath: self requestContext consumer upToEnd.</div>
<div><span class="Apple-tab-span" style="white-space:pre">	</span>self request isGet ifTrue: [</div><div><span class="Apple-tab-span" style="white-space:pre">		</span>url purgeSeasideFields].</div><div><span class="Apple-tab-span" style="white-space:pre">	</span>self response redirectTo: url</div>
</div><div><br></div><div>With the requirement that the WAUrl&gt;&gt;purgeSeasideFields is moved from Pier-Seaside-Mapping into Seaside-Core-HTTP.</div><div><br></div><div>Thoughts?</div><div><br></div><div>Nick</div><div>
