map provides null parent

[sbussard]

I have this simple map function, but the parent is null while everything else is set.

map: function(parent, element, key, val) { 
  console.log(parent);
  return true;
}

at first glance, this looks like a first run issue. can you provide some more detail?

I know this is a lot, but I don't know what you need to know. Here's my whole code. When I put console.log(parent); in the map function on line 27 of the code it will only write null in the js console on the latest chrome.

(function($){
    var people;
    var editMode = gup('edit'); //boolean

    // http://www.netlobo.com/url_query_string_javascript.html
    function gup(name) {
      name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
      var regexS = "[\\?&]"+name+"=([^&#]*)";
      var regex = new RegExp( regexS );
      var results = regex.exec( window.location.href );
      if( results == null )
        return "";
      else
        return results[1];
    }

    $.fn.weld = function(data, config) {
        this.each(function(index,value) {
            weld(this, data, config);       
        });
    };

    $.get('/members',function(result){
        people = result;
        $('.people .person').weld(people, {
            map: function(parent, element, key, val) {
                if(val == "") val = " ";
                return true;
            }
        });
    });

    if(editMode) {
        var fieldSelector = $('.person > div:not(.pin)');
        fieldSelector.attr('contenteditable','');
        fieldSelector.addClass('editable');

        fieldSelector.live('click',function(){
            var t = $(this);
            this.before = t.text();
            t.focus();
        });
        fieldSelector.live('keypress',function(e){
            var t = $(this);
            var code = (e.keyCode ? e.keyCode : e.which);
            if(code == 13) {
                t.blur();
            }
        });
        fieldSelector.live('blur',function(){
            var t = $(this);
            var c = t.parent().children();

            var firstname = c.filter('.firstname').text();
            var lastname = c.filter('.lastname').text();
            var pin = c.filter('.pin').text();
            var phone = c.filter('.phone').text();
            var email = c.filter('.email').text();

            var newjson = {
                firstname: firstname,
                lastname: lastname,
                pin: pin,
                phone: phone,
                email: email
            }

            $.post('/members',newjson,function(result){
                console.log("Change applied, and " + result);
            });
        }); 
    }

})(jQuery);

can we see the output you are seeing from:

map: function(parent, element, key, val) { 
  console.log(parent);
  return true;
}

[sbussard]

The output changes a bit for each row, but here's an example:

    null <div class=​"col email">​</div>​ "email" ""

@sbussard, thank you! We'll look into it!
