+<p>Until the end of the 1990s web browsers are usually single threaded and
+only had one window. But in the last years browsers supporting multiple
+windows or even tab became the standard. Since those days lots of
+efforts went into uniquely identifying a single browser window on the
+server side. Sadly browser windows still lack of a native windowId, thus
+maintaining web application data in @SessionScoped backing beans is
+still used in most of the cases.</p>
+</div>
+</div>
+<div class="sect3">
+<h4 id="_how_jsf_2_changed_the_world">How JSF-2 changed the world</h4>
+<div class="paragraph">
+<p>The MyFaces Orchestra community did a good summary about the various
+ways to handle multiple window support in JSF Applications. Those
+findings are still valid and up to date, but the environmental
+conditions have changed slightly since then. It is easy to pass a
+windowId around with a POST request, but it gets tricky with GET
+requests. Due to the new JSF-2 ability to use bookmarkable URLs and deep
+links, a typical JSF-2 application contains much more GET links than we
+used to see in JSF-1, thus we have far more href links to cope with.</p>
+</div>
+</div>
+<div class="sect3">
+<h4 id="_standard_windowid_handling">Standard windowId Handling</h4>
+<div class="paragraph">
+<p>With a classical approach we would not be able to simply add a windowId
+parameter to such links because if the user would open the link in a new
+browser window or tab, we would carry the windowId - and thus the window
+scope - over to the new browser tab/window. The classic solution was to
+omit the windowId for all GET links, but by doing this we would now
+loose the window scope far too often with JSF-2! Marios summary also
+contains a method to prevent this problem by storing a value directly in
+the browser window via JavaScript. Usually this is rendered and executed
+in the same page as the user form. See the "Post-render window
+detection" paragraph for a more detailed description. The major downside
+of this solution is that we might already pollute 'foreign' beans (and
+destroy their information) while rendering the page, which means this is
+not feasible as general solution.</p>

+<div class="paragraph">
+<p>Each GET request results in an intermediate small html page which checks
+if the browser tab fits the requested windowId. When the windowId is
+valid, a unique token (called <code>dsRid</code>) will be generated for the current
+request and added to the URL. In addition a cookie with with the
+dsRid/windowId will be added. On the server side, the verified windowId
+will be extracted from the cookie. For POST request detection, the
+windowId will be added as hidden input to all forms.</p>

+<p>Having the windowhandler.html site rendered between requests sometimes
+leads to some 'flickering' if the destination page takes some time to
+load. The browser first renders our windowhandler and only after that
+the original page will get loaded. This effect may be minimized by
+branding the windowhandler.html page and providing an own one with a
+bgcolor which matches your application. For html-5 aware browsers we
+also got rid of this flickering by storing away a 'screenshot' of the
+first page in onclick() and immediately restore this 'screenshot' on the
+intermediate windowhandler.html page. Technically we do this by storing
+away the and css information into the html5 localStorage and restore them on the
+intermediate page. We also introduced a WindowConfig which is able to
+parse a request and decide upon the UserAgent or any other information
+if a client will get an intermediate page or if he gets the result page
+directly.</p>

+<h3 id="_intro_2">Intro</h3>
+<div class="paragraph">
+<p>Type-safe view-configs are static configs which can be used in
+combination with every view-technology which is based on Java. Currently
+DeltaSpike itself provides an integration for JSF, however, the basic
+concepts are independent of it. (Since DeltaSpike provides the default
+integration only for JSF, the whole documentation for view-configs is
+located here.)</p>
+</div>
+<div class="paragraph">
+<p>Thanks to features like multiple (meta-data-)inheritance via interfaces,
+it provides a powerful approach to bind meta-data to one or multiple
+views. In case of the JSF integration it&#8217;s possible to provide e.g.
+type-safe meta-data for security, navigation, callbacks for
+view-controllers. Beyond configuring view (/pages) via this concept,
+it&#8217;s also possible to use the (view-)config classes for type-safe
+navigation. Since it&#8217;s std. Java, you can benefit from any Java-IDE and
+you don&#8217;t need special IDE-Addons to use it efficiently.</p>
+</div>
+<div class="paragraph">
+<p>Even the concepts provided by modules (of DeltaSpike itself) are based
+on the basic API provided by the Core. So it&#8217;s possible to introduce
+custom concepts the same way DeltaSpike itself does.</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_motivation">Motivation</h3>
+<div class="paragraph">
+<p>Instead of learning the concepts and rules of view-configs provided by
+DeltaSpike, it might be easier for simple demos to just type some
+simple(r) strings. So why should you use something which is slightly
+more work <strong>initially</strong>?</p>
+</div>
+<div class="paragraph">
+<p><strong>The short answer is:</strong></p>
+</div>

+<p><strong>The long answer is:</strong></p>

+<div class="paragraph">
+<p>You can benefit from it from the first second:</p>
+</div>
+<div class="ulist">
+<ul>
+<li>
+<p>It&#8217;s type-safe &#8594;</p>
+<div class="ulist">
+<ul>
+<li>
+<p>the Java compiler ensures that you don&#8217;t have typos at the final usages (and the rest can be checked during bootstrapping of the application)</p>
+</li>
+<li>
+<p>you can benefit from the auto.complete features of any modern Java IDE.</p>
+</li>
+</ul>
+</div>
+</li>
+<li>
+<p>If you change the name of a file/folder, you need only one (easy) code-change in a single place and your (std. Java-) IDE will do the rest for you (= update all usages) without a special plug-in</p>
+</li>
+<li>
+<p>It&#8217;s possible to restrict the navigation target &#8594; you can ensure that the navigation target is still the intended one (e.g. after a refactoring)</p>
+</li>
+<li>
+<p>You can configure meta-data in a central place (which can get inherited via <strong>multiple</strong> inheritance based on Java interfaces)</p>
+</li>
+<li>
+<p>Easier for developers to find usages</p>
+</li>
+<li>
+<p>Allows easy(er) refactorings and maintenance</p>
+</li>
+<li>
+<p>You can use your IDE more efficiently esp. in large projects (there are some users who initially switched to it, because their tools for displaying the config they had before open large config files very slowly&#8230;&#8203;)</p>
+</li>
+<li>
+<p>Modern Java IDEs show inheritance of interfaces and classes in a nice way. Since the view-config is based on std. classes and interfaces, you can benefit from it easily.</p>

+<div class="paragraph">
+<p>Advantages which are planned for later (= currently not supported):</p>

+<ul>

+<p>It&#8217;s possible to check if the configured folders and files really exist during/after the bootstrapping phase of the application (currently it isn&#8217;t implemented, but it&#8217;s possible to do it).</p>
