Hi,
I would have to take a look at the TreeStrategy to see what is happening. In the meantime you can always write a custom Converter to handle this particular map.

Hi,

I would like to serialize a properties map like this:

    @ElementMap(entry="parameter", key="name", attribute=true,
inline=true, required=false)
    protected Map<String, Object> parameters;

If this map has an Integer or String object then everything is ok.
If I put a String[] object to the map then I got the following exception:

It seems that the TreeStrategy.writeArray method returns null when try
to call Class<Objecŧ>.getComponentType.

Is there a solution to serialize a String array or a collection inside this map?

Thanks,
Tamas
