Hi there - Have you considered using the Java methods that are available from the Expression Editor?  Those methods are powerful and will help you manage your data fields.  Let me know.

You've defined your field to be of type String so the value will be stored as a String.

I've got another method by controling in java code:

define this field as String

override the getFieldValue(JRField paramJRField) in your relative dataSource class

when you get the value in your java code ,you can convert them to a string.
