Do you know of a way on a REST response to return a property of Array type without defining a value?

DIMENSION Counties(1)
ADDPROPERTY(loResults,'Counties[' + TRANSFORM(1) + ']')

The default value seems to be "false" rather than "undefined" even though no value was specified. And assigning .null. returns just that... null.

Or do I need to trap for this in the Javascript on the client side?

Thanks

Arrays can't be returned in FoxPro - it's an illegal operation.

If you're serializing to JSON return a Collection or wwCollection or a cursor, all of which will be serialized into a JSON array. If necessary you can use ArrayToCollection().

Thanks for the answer, I am returning a collection so I've added the array to it but since it can be empty, I still need a value that will never come up as real data. I think I will assign .null. as a value and then trap for it on the client where I will convert null to unassigned.

Thank again for your thoughts.

The way to return empty arrays is to return an empty collection. Usually that's better because you don't have to have the extra null check.
