Re: flaky error: Error - tag.getAsString : component context is not defined
Thats good you sorted it out, and that you posted the cause/solution back to the list. We could do with some Wiki pages where people could record errors and their cause/solution - kind of "knowledge base", I'm sure it would help alot of people - it can be difficult to find these kinds of things from trawling the list archvies.

RE: flaky error: Error - tag.getAsString : component context is not defined
Niall, thanks for your response. It would appear that this is the result of the user having javascript disabled on their browser. Also, once we established that the users were not actually submitting their forms, but were getting the error as soon as they clicked on the link, it made it much easier to narrow down the problem. This was the link: Add Contact Form The onclick is being ignored, and the
Re: flaky error: Error - tag.getAsString : component context is not defined
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.

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. The error appears to be about tiles, but that just doesn't seem logical, since why wouldn't everybody be getting the error? Before I post the error message, etc, I should point out that the key to these users getting this error would seem to be a few fields on the form that are hidden unless they click on a link to show them. The point being is that they need to select a company and a contact person for the company. The company is in a drop-down box and when a company is chosen, I populate the contact drop-down box with the contacts for the selected company. But if the contact they want isn't there, they can click on a link that then allows them to enter the contact's name, phone and email. The contact fields are conditionally validated upon submit for full name, proper phone/email. Like I say, it works most of the time, but the same 2 or 3 users keep getting these problems. If they don't use the fields to add a contact, the form will submit fine. If they do use the extra fields they get the error as described... The error message in the log is: " 4/20/04 3:26 PM barts-web: Servlet error javax.servlet.jsp.JspException: Error - tag.getAsString : component context is not defined.
