[Vala] Marshalling stuff into JSON

[Magnus Therning <magnus therning org>]

I'm having some problems with json-glib-1.0.  As things went *very* pear
shaped when I tried to marshal an object I have I've limited myself a little.
Currently I'm working on the following short example:

  using Json;

  int main( string[] args ) {
      Generator json_gen = new Generator();
      Json.Node arr_node = new Json.Node( NodeType.ARRAY );
      Json.Array arr = new Json.Array();
      Json.Node obj_node = new Json.Node( NodeType.OBJECT );
      Json.Object obj = new Json.Object();
      Json.Node mem_node = new Json.Node( NodeType.VALUE );

      mem_node.set_string( "hello" );
      obj.add_member( "mem", mem_node.copy() );
      obj_node.set_object( obj );
      arr.add_element( obj_node.copy() );
      arr_node.set_array( arr );

      json_gen.set_root( arr_node.copy() );
      json_gen.to_file( "test2.js" );

      return( 0 );
  }

Unfortunately it doesn't produce the expected result:

  % cat test2.js
  [ { "mem" : "" } ]

I was expecting to see "mem" have a value of "hello".  I get a few errors when
running the binary, so I suspect somehing's not quite right:

(process:11711): GLib-GObject-WARNING **: gvalue.c:185: cannot initialize 
GValue with type `gchararray', the value has already been initialized as 
`gchararray'

Anyone with any ideas?
