[jira] [Commented] (TAP5-2441) PageRenderLinkSource fails in cron job

["Jochen Kemnade (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TAP5-2441?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14371251#comment-14371251 ] 

Jochen Kemnade commented on TAP5-2441:
--------------------------------------

I've got a similar issue with my minification cache warming module. You can work around it by storing a mock request in the {{org.apache.tapestry5.services.RequestGlobals}} service at the start of your job.

> While trying to use PageRenderLinkSource in a cron job failure occurs. It appears as if it doesn't use the base url configurations from the AppModule, but rather the request. The request throws a null pointer.
