Simple Xml Elementlistunion - Two Generic Lists Not Allowed?

I am trying to desrialize an xml through simple framework. I have two lists whose types will be known only at runtime. So I used @ElementListUnion. Customer.java @ElementListUnion

Solution 1:

You haven't set a value for entry, so Simple can't decide which class you are using. See here:

@Root(name = "Customer")
public class Customer
{
    @ElementListUnion(
    {
        @ElementList(entry = "thingValue", inline = true, type = Thing.class),
        @ElementList(entry = "anotherThingValue", inline = true, type = AnotherThing.class)
    })
    List<Object> things;


    @ElementListUnion(
    {
        @ElementList(entry = "thingValue", inline = true, type = Thing.class),
        @ElementList(entry = "anotherThingValue", inline = true, type = AnotherThing.class)
    })
    List<Object> anotherthings;

}

Each @ElementList requires an entry, thats the tag which is used for the element:

<Customer><thingValue>...<thingValue/><!-- That's a 'Thing' --><anotherThingValue>...<anotherThingValue/><!-- That's an 'AnotherThing' --></Customer>

But make shure you dont name the entry like the class, so entry = "thing" may fail.
