Elementlistunion - Simple Xml Giving Duplicate Annotation For Generic List Objects

I am trying to deserialize a List field using elementlistunion Customer.java @ElementListUnion({ @ElementList(inline = false, type = Thing.class), @ElementList(inline =

Solution 1:

I don't know why are you trying to make two classes in ElementsListUnion. You can use

@ElementList(inline = false, type = Thing.class) 

instead of this or

@ElementListUnion({ @ElementList(inline = false, type = Thing.class, required = false),
        @ElementList(inline = false, type = AnotherThing.class, required = false) }) 

if you don't send two elements types every time.
