[flexcoders] regular expression tester says it works, but it doesnt????

[flexaustin]

pattern = new RegExp('(?<=\"name\":\").*(?=\",\"\w*:)', 'i');
var resultArr:Array = pattern.exec(data);

resultArr ends up equaling null;

But if you check this:  (?<=\"name\":\").*(?=\",\"\w*:) using
http://gskinner.com/RegExr/ it says it works using this data

"error":32,"count":47,"group":true,"connection":39,"warning":3,"name":"Workstations","title":"Workstations","model":"workstation","ticket":1,"type":"TagCategory","id":1

So why is it not working in my code? If anyone has any suggestions I
would appreciate it.  I have been trying to get this to work for 10
hours straight.

TIA
