Re: [Hypercontent-users] How to read groups.xml from the CAS server.

[Alex V. <al...@bi...>]

The ajax will not require any direct involvement from uPortal.  You  
would define a pipeline like this in your project's /config/ 
pipelines.xml (or in the bootstrap repository if you want to have  
this available for all projects)

<pipeline basedir="/" binding="all" content-type="text/xml"  
mode="page-edit-link" >
		<exec stage="org.hypercontent.project.engine.stage.VelocityStage">
			<with-param name="source" value="/skin/page-edit-link.vm" />
			<with-param name="localize-with" value="/l10n/listing" />
		</exec>
	</pipeline>

Then, create the file /skin/page-edit-link.vm in your project  
repository or the bootstrap repository and put something like this:

<div>
#if ($session.Authenticated && $session.hasPermission 
($project,'write',$request-path))
<a target="hc2-window" href="${abs-project-base}${request-path}? 
mode=interactive&amp;screen=edit">edit</a>
#end
</div>

Finally in your XSL that generates the markup presented in the portal  
put something like:

<script type="text/javascript" language="javascript" src="${abs- 
server-base}/js/common.js">
</script>
<script type="text/javascript" language="javascript" src="${abs- 
server-base}/js/ajax.js">
</script>

<div id="page-edit-link-div"></div>

<script type="text/javascript" language="javascript">
            loadToElement(document.getElementById('page-edit-link- 
div'),'<xsl:value-of select="concat($abs-project-base,$request-path)"/ 
 >?mode=page-edit-link');
</script>


and make sure you have declared the XSL parameters

<xsl:param name="abs-project-base"/>
<xsl:param name="abs-server-base"/>
<xsl:param name="request-path"/>

This will load the output of the page-edit-link pipeline, which  
performs the authorization check, directly into the target div,  
presenting the edit link if there is one.

Let me know if any part is unclear!
