Re: [Simple-support] Deserializing Map<String, NotPrimitiveType> with "Simple XML"

Try to serialize an instance and take a look at the structure. This should match the input. For below, you can only use inline with primitive types. For an object the value will be a child element.

Subject: [Simple-support] Deserializing Map<String, NotPrimitiveType> with "Simple XML"

Hi,

Is it possible to deserialize Map<String, MyType> with Simple xml? How can I do that?

I checked examples section but it contains example only for Map<String, SomePrimitiveType>.

I tried to do it myself:

Java classes:

@Root
public class Content {

    @ElementMap(entry="page", key="id", attribute=true, inline=true)
    //@ElementMap(entry="page", key="id", attribute=true, inline=true, valueType=net.edyoucare.krisenkompass.Page.class)
    public HashMap<String, Page> pages;

}

@Root
public class Page {

    @Attribute
    private String id;

    @Attribute
    private String layout;

}

Xml:

<?xml version="1.0" ?>
<content>

  <page id="root" layout="text_with_pdf_link">test</page>
  <page id="root2" layout="text_with_pdf_link">test</page>

</content>

Deserializing code:

Serializer serializer = new Persister();
Content result = serializer.read(Content.class, br);

The code above runs without any exceptions. It produces Content instance with a map which has two entries with correct keys. But these keys are map to the null values :(
So the map in Content.pages field looks like {root=null, root2=null}.

I don't have any ideas how to force it to create Page object, and map the keys with that object.

Thanks,
Dzmitry
