It’s kind of difficult to understand why they cannot get JSON right:
Now the surprise: ColdFusion 9.0.1 says goodbye to the number format in JSON. All numbers in JSON will become strings once ColdFusion gets its hand on the data. There are no more numbers. 10 becomes “10”, 10.2 becomes “10.2” etc. Even though the patch notes stated that differently. And i still believe it was not Adobe’s intention to remove numbers but somehow this flawed implementation slipped in.
As the author puts it:
ColdFusion 9.0.1 is essentially disqualified to be used with NoSQL datastores where JSON is involved.
