SpinJsonNode add/remove elements to SpinList

Hi Maria, whenever Spin gives you a java.util.List, this is a copy of a collection of elements, not a view on that element collection in the original datastructure. So modifying the list will not do anything more than that. See the following link for how to add an element to a JSON array and other examples: Cheers, Thorben

So you can use

spinJson1.remove(obj);

to remove a specific object

or

spinJson1.removeAt(index);

to remove element at a specific index.

or simply assign it to an empty array to clear all elements

In your case, you could iterate on elements of the second list and do

spinJson1.remove(obj);
on each object
