Sorry, don't have an answer/solution for you, but I am left me wondering what was the result of the action that ran? The tiles stuff is done at the end, after the Action - so if your users submitted a form then did the Action do its stuff OK and then fail forwarding to your tiles definition? If so what do your struts-config,xml and tiles-defs.xml look like for that forward?
I believe the TilesRequestProcessor sets the component context - is it possible that whatever your users are clicking on is going straight to a jsp and not going through an Action and therefore also not going through the TilesRequestProcessor? I would also go see (if possible) what exactly those users are doing, perhaps they are doing their stuff in a way noone else is - in my experience users at best miss out crucial information and at worst downright lie about what they've done :-) Niall ----- Original Message ----- From: "Janice" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, April 21, 2004 7:03 PM Subject: flaky error: Error - tag.getAsString : component context is not defined > I've got a struts app in production and a couple users get this problem when > submitting a certain form.
