Ah yes. The original implementations didn't properly manage child arrays, so it sounds like you were in fact running the original code...
Glad it's working - you had me worried there for a minunte until I double checked...

Hi Rick
Problem sorted. I could not work it out why you were not getting the same results as I did.
Recompiled classlibs etc and all good.
Thanks for looking at it.
Yes I ran your code and it all failed because it referenced the wrong items. The snippet I posted worked once I changed that bit of code. The next bit of code failed as it should...

Hi Rick
Did you run my code ?
I agree that register_sale_products[2] should not exist but it does. The code does not fail in this example. It only fails when demonstrating the 3rd issue.
Tks
Rodney
Just taking a quick looks: your logic in retrieving the values is wrong.
I'm not clear when you say that the product collection item shouldn't exist - of course it should it's there in the JSON. The problem with the first code is that there is no value property on the product, it's on the product's attributes. You need to drill into the attributes and this works fine returning the proper values of line_note and empty.
loProduct = loCust2.register_sales[1].register_sale_products[1] ? loProduct.Attributes[1].Name ? loProduct.Attributes[1].Value
The next block of code references an element that doesn't exist (register_sale_products[2]) and rightly that code fails.
Same thing with the next block code.
I stopped at this point, because it seems you're looking at something different than what's actually running there.

Please post some code for each of those points that demonstrates. I don't want to wade though your hierarchy.
Please use the code markup features here in the forum.

Hi
I am having some issues using DeserializeJson as follows:
1. An embedded array creates a new element in the array (collection) above it and not as a collection in its own level. (bit confusing) See 'Attributes' in example below. It creates 2 elements in register_sale_products, 1 which just has the attribute element's values and a second which is correct.
2. An empty array [] creates an object with the parent's elements. See 'Register_sale_payments' (1st record set) in example.
3. If there is more than one record set in the Json, PassArrayJson gives you a loValue is not an object.
To test points 1 and 2 you will need to remove the second record set from the example below.
Any advise please.
Many Thanks
Rodney
