Get drawing table name via J-Link

I have a drawing containing 3 tables, each with its own name, say "Table1", "Table2" and "Table3".

I am trying to get table names via J-Link; here follows my sample code:

Tables drwTables = drawing.ListTables();

if (drwTables != null) {

    for (int i = 0; i < drwTables.getarraysize(); i++) {

        printMsg("Table Id: " + drwTables.get(i).GetId());

        printMsg("Table name: " + drwTables.get(i).GetName());

    }

}

ListTables() correctly returns 3 Tables; moreover I guess also GetId() returns their correct ID values (0, 1 and 2 respectively). On the contrary, GetName() always returns null.

What's wrong with my code? Which is the right way to get table names?

Thanks!
