[flexcoders] Null object doesnt exist? What is going on?

[flexaustin]

Ok, in my custom component I have this line: 

// root node to start with
private var strtRoot:IThingy;

Later in a function call from init() I call this:

strtRoot = new Thingy(somearrary[1]);

I get a null object error on strtRoot. I am try to create strtRoot why
am I getting this error? 

I use this code in another area and it runs fine, but when I use it to
create another object it throws an error. And yes I have check that
somearray[1] exists.

TIA
