    Hi Anonymous,

    There's no support for complex types as property values. Most developers will use text as the data type (as you're already doing), hide the property during enumeration and JSON.stringify the array before it's persisted. Use JSON.parse when you read it back.

    You may be better with the property default as "[]" so that an 'empty' property will parse to an empty array and be ready to work with in your code (or you could coalesce a default null property value to an empty array).

    Regards,

    Daniel
