OrientDB javascript function, "save" on getDataBase not working -

i'm following tutorial http://pettergraff.blogspot.fr/2014/01/getting-started-with-orientdb.html

and on fourth part, we're suppose create javascript function push "members" in database.

i know tutorial old , i've been through issues, instance had delete block

<handler class="com.orientechnologies.orient.graph.handler.ographserverhandler">             <parameters>                 <parameter value="true" name="enabled"/>                 <parameter value="50" name="graph.pool.max"/>             </parameters>         </handler> 

from orientdb-server-config.xml, make following code work :

var db = orient.getdatabase(); 

is normal?

now line okay, i'm having trouble, here "my" code :

var db = orient.getdatabase();  db.begin();  (var = 0; < n; i++) {   var name = prefix + "_" + i;   var email = name + "@gmail.com";   var member = {     "@class": "member",     "name": "robin",     "password": "robin",     "email": "robin"   };   var result = odocument.save(member); } db.commit();  return 0; 

the problem on "save" method

var result = db.save(member); 

it's saying method ambigus, don't know :)

here error (in french, i'd in english didn't find out how change de language on orientdb interface)

does knows do? thank !

something quite equivalent using graph api:

var db = orient.getgraph(); var member = db.addvertex("class:member"); member.setproperty("name", "robin"); member.setproperty("password", "robin"); db.commit();  return;
