I am using analytics API. I parse resuting Json through Report Parser Class. This worked when there is no currency field selected. As soon as I fetch currency field in report. This parser class gets crashed with message "Illegal value for primitive" at line

reportData = (ReportWrapper)JSON.deserialize(jsonString, ReportWrapper.class);

Please find below both Parser class and Json string with currency field which when passed gets crashed.
Could you please help me modifying the parser class to accomodate currency field
(There is also some difference for currency fields and other fields which comes like array/object -- see below vs normal field
Currency = {"label":"$10.00","value":{"amount":10,"currency":null}},
Normal field = {"label":"1/11/2015","value":"2015-01-11"} )
