[jira] Commented: (TAP5-1015) Add support to return other pages from onActivate()

["Howard M. Lewis Ship (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TAP5-1015?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12833362#action_12833362 ] 

Howard M. Lewis Ship commented on TAP5-1015:
--------------------------------------------

I see this as supporting a new return type, say, StreamPageContent, that would trigger the rendering of a particular page.

The use case here is that a given page's activation context represents a particular entity and the entity does not exist; it would be nice to be able to leave the URL unchanged but stream some other page's content (i.e., the "Foo Entity Not Found" page).

> Currently, onActivate() has no ability to delegate the rendering to another page or stream without a redirect. It would be really helpful to support more return types from this method. 
> Motivation: if the activation context is faulty you might want to keep the url the way it is and still be able to render a different page than the current page.
