[jira] Commented: (TAP5-986) sendError in onActivate / Tapestry error dispatching

["Josh Canfield (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TAP5-986?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12921959#action_12921959 ] 

Josh Canfield commented on TAP5-986:
------------------------------------

In 5.2 there is an HttpError object that can be returned by an event handler to send an error response to the client. Does that meet the requirements of this defect?

> RestoreDirtySessionObjects is generating a NullPointerException with this line :
> Session session = request.getSession(false);
> It seems that the dispatching is done in one single thread, then the initial class to RestoreDirtySessionObjects is delay, and request object is lost.
