JSON.generate'd data produces error in AWS 2.3.2

[mistergibson]

Hey There,

I'm attempting to ship JSON data over SOAP to AWS. Now, if I just send JSON data back to my test script - it comes through just fine, all is good. However, if passed JSON data over the SOAP interface as an input (and the expects is set to :string) it barfs out this error:

$transactions.transfer_funds({:from_acct => "0", :to_acct => "1", :amount => 0.0})

Any ideas on how I can work around this problem, or have I found a bug?

Thanks in advance :)
