[ http://issues.apache.org/jira/browse/COCOON-1963?page=all ]
Alexander Klimetschek updated COCOON-1963:
------------------------------------------
Attachment: RedirectTransformer.java
The RedirectTransformer with a different package name. Should IMHO go into
cocoon ajax, just next to the BrowserUpdateTransformer.
> Add a redirect action to the browser update handler

> Key: COCOON-1963
> URL: http://issues.apache.org/jira/browse/COCOON-1963
> Project: Cocoon
> Issue Type: New Feature
> Components: Blocks: Ajax
> Affects Versions: 2.2-dev (Current SVN), 2.1.10-dev (current SVN)
> Reporter: Alexander Klimetschek
> Attachments: BUHandler.js, RedirectTransformer.java
>
>
> In some situations you want to redirect the browser to a different page
> inside a cforms action, eg. you have a REST-style interface and create
> something under the URL /new (which shows a form to enter your new data) and
> on save you want to redirect the user to a page where that new data is stored
> (e.g. /foobar42). To do so in an ajax-environment, where the save action will
> be answered with a browser-update XML snippet, you need a separate action in
> the browser update handler. This patch adds the handling of a simple
> "redirect" action to the BUHandler.js:
> <bu:document>
> <bu:redirect uri="foobar42" />
> </bu:document>
> If you want to have a fallback solution for non-AJAX cases, you need to
> trigger a normal HTTP redirect from your pipeline. This must happen when this
> bu:redirect is inside the XML stream, otherwise all content should be
> serialized to the browser. That functionality is provided by the attached
> RedirectTransformer. The usage would be like:
> <select type="ajax-request">
> <when test="false">
> <transform type="redirect" />
> </when>
> </select>
> The server-side javascript snippet for the save action should look like (form
> is the Form object and documentID="foobar42"):
> if (newDocument) {
> form.getWidget().endProcessing(false);
> cocoon.redirectTo("cocoon:/redirectTo/" + documentID);
> }
> There should be a pipeline that matches "/redirectTo/*" and that serves the
> bu:document like above (eg. via a jx template to insert the documentID).
