Ahh, I bet I know what is happening. ViewStack uses deferred instantiation by
default. This means that "resultsInstance" literally does not exist until the
user first navigates to that view. So any attempt to access variables or
anything else in that component will cause an error if it has never been viewed.

The quick fix is to set creationPolicy="all" on the view stack.

The purpose of the default deferred instantiation is to imporve the users
perception of speed when the app initializes; you take a small hit the first
time you nav to a view, but the app loads much faster.

You can do a lot with creation policy, but save that for later.

Also, when referencing components, you do need to travel the hierarchy. so if
you wanted to access a variable in one child from a sibling, you would do this,
it is the long form:

var complaints:String =
mx.core.Application.application.resultsInstance.co mplaints;

If you pass a reference to the application into each child, which I recommend:
var complaints:String = app.resultsInstance.complaints;

And if you pass in a ref to the sibling:
var complaints:String = ri.complaints;

Instead of using Cookies what i want to do in Flex is have a global variable
that will be avaiable anywhere in the application. So when a user logs in the
userID variable will have the value of 2 and can be accessed anywhere in the
application is this possible?

Thanks...

There are several ways to do this. The simplest is to create apublic variable
in the main application scope(not in a function), use
Application.application.myVar to reference that var. that reference will work
from anywhere, including apps loaded using swfLoader. Import
mx.core.Application into each component where you need that. I create a var in
each component, _app:application, and assign it in an init function. Just
saves some typing.

Another way is to use a singleton data model class. It is a more flexible
solution than global vars.
