I think this is happening because you are trying to access a property or method of a null object reference.
:) I couldn't help myself. But really, if this is happening after a deploy, maybe one of your web service calls or server data calls are failing and in your code you are not checking for valid data before operating on it. Make sure the paths you are using work on the server too, and if your data calls are to web pages that can be viewed in a browser directly, use a browser to view them to make sure there are no errors preventing valid data from being returned in the production environment. --- In [email protected], "sarah_e_boys" <[EMAIL PROTECTED]> wrote: > > I get the following error when I deploy and access my Flex app on a web > server.
