Subject [jira] [Commented] (JS2-1219) When there is any portlet fragment which refer to a non-registered portlet definition, the page is not rendered with "Content not available" message.
Date Tue, 30 Aug 2011 15:09:38 GMT

    [ https://issues.apache.org/jira/browse/JS2-1219?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13093800#comment-13093800
] 

Mansour Al Akeel commented on JS2-1219:
---------------------------------------

This issue is still there in JS-2.2.1 binary installer. When A portlet fragment exists on
the page, and the portlet application is deleted, it shows a portlet with:

"Content is not available" text, and within that portlet, additional portlets.

> When there is any portlet fragment which refer to a non-registered portlet definition,
the page is not rendered with "Content not available" message.
> For example, when a psml page refers to the bookmark portlet, but apa-demo is not deployed,
this error occurs.
> The cause is because a portlet window is created without portlet definition when it cannot
find a portlet definition from the portlet registry.
> So, during rendering, we shouldn't assume that a portlet window will return a valid portlet
definition every time.
> By the way, the exception traces are logged like the following:
> 29.09.2010 22:29:34 ERROR [org.apache.jetspeed.request.JetspeedRequestContext.createPortletWindow():680]
Failed to retrieve Portlet Definition for demo::BookmarkPortlet
