The cfwheels documentation says that for using hasManyRadioButton() the property field is required. But in their example they haven't used property.
Following is the example provided by cfwheels documentation.
<!--- Show radio buttons for associating a default address with the current author --->
<cfloop query="addresses">
#hasManyRadioButton(
label=addresses.title,
objectName="author",
association="authorsDefaultAddresses",
keys="#author.key()#,#addresses.id#"
)#
</cfloop>
Is the property attribute required or not? What is the right convention to use this function?
