NetBeans-JavaFX-Soma:  #188

Steps to reproduce:

- Copy the code to the editor:
-------------------------------------
var a = 10;
var b = a + 10;
-------------------------------------

- Select the 'b' variable
- Invoke Refactor->Safely Delete 
- Press Refactor on the dialog 

The NPE pops up.
Comment 3 Alexandr Scherbatiy 2010-03-17 09:06:31 UTC 
The same is if safely delete the 'f' function from the code:
-------------------------------------- 
class A{
    public function f() {
    }
}
--------------------------------------
Comment 4 Alexandr Scherbatiy 2010-03-17 09:07:17 UTC 
The same is if safely delete the 'A' class from the file:
------------- Main.fx  ----------------- 
class A{
    public function f() {
    }
}
--------------------------------------
