[Opensync-devel] change handling

[deloptes <del...@ya...>]

I need information about following

1. when do you call  osync_data_set_objtype( )

2. do I need to call update_change in the example below

3. when I call 
    osync_change_set_data ( change, data );

where do I call     
    osync_data_unref ( data );

I'm trying this

   osync_change_set_data ( change, data );
   osync_data_unref ( data );

   osync_context_report_change ( context(), change );
   osync_change_unref ( change );

but I get i.e.
