access in your scripts as the global variable <tt>cocoon</tt>, for example
like
this:</p>
--- <pre>
--- var value = cocoon.request.getAttribute("blah");
+++ <pre> var value = cocoon.request.getAttribute("blah");
</pre>
<p>The <tt>Cocoon</tt> object supports the following properties and
functions:

otherwise it is resolved relative to the current sitemap. The URI should not
contain a scheme (such as cocoon:).</p>
--- <p><tt>bean</tt> is a context object which can be accessed inside this page
to
--- extract various values and place them in the generated page.</p>
+++ <p><tt>bean</tt> is a context object which can be accessed either inside
this
+++ page to extract various values and place them in the generated page or in
the
+++ sitemap to use values as parameters for actions or transformers.</p>
+++ <p class="note">Use <tt>value="{flow-attribute:name}"</tt> in any parameter
tag
+++ in the sitemap to access a value from the bean.</p>

<p>If provided, the <tt>postPipelineCode</tt> function will be executed
after
pipeline processing is complete but before the script is suspended. You can
use
this to release resources that are needed during the pipeline processing but
should not become part of the continuation. For example:</p>
--- <pre>
---
--- function processPage() {
+++ <pre>function processPage() {
var id = ...
var bizData = ...
var uri = ...
(68 equal lines skipped)
<p>For example:</p>
--- <pre>
+++ <pre>function processPage() {
--- function processPage() {
---
var bkm = cocoon.createWebContinuation();
var biz = getBizData();
cocoon.sendPageAndWait("uri",

<p>Dispose an object that has been created using <tt>createObject</tt>.</p>
+++ <h3>exit</h3>
+++
+++ <p><em>Function</em> exit()</p>
+++
+++ <p>Exit the current flowscript invocation.</p>
+++
+++ <p>There are some flowscript use cases where we want to stop the current
+++ flowscript without creating a continuation, as we don't want the user to go
back
+++ to the script and return from the current function.</p>
+++
+++ <p>An example is a "login" function where the caller function expects this
+++ function to exit only if login is successful, but that has to handle e.g. a
+++ registration process that includes a "cancel" button.</p>
