I would like to have a masked password field in an EditorGrid. THis is my current code, but it is not masking the password:

Code:
        column = new ColumnConfig("password", "Password", 100);
        TextField<String> passwordField = new TextField<String>();  
        passwordField.setAllowBlank(false);
        passwordField.setPassword(true);
        column.setEditor(new CellEditor(passwordField));
        columns.add(column);
Any ideas?
