jquery data-attribute works randomly

Question

I have a function which is called on mouse out. It checks whether the element is now "dragged" or in process of editing. If not it should remove the active state.

This is how it looks.

function onMouseOut() {
        console.log("mouse out");
        if ($(this).find(".content").attr('data-editing') != "true" && $(this).find(".content").attr('data-dragging') != "true") {
                console.log("no edit, no dragging");
                removeActive($(this).find(".content"));
        } else {
                console.log("edit: " + $(this).find(".content").attr("data-editing"));
                console.log("dragging: " + $(this).find(".content").attr("data-draging"));
        }
}

The element is inside a sortable. It does not break the code above and I can sort it as many times as I want. But when I add the "connectWith" and shift sender it totally breaks.

Then my output to console is as follows:

mouse out
edit: undefined
dragging: undefined

Now, how is that even possible?

EDIT:

Ok here comes the markup:

<div id="body">
    <section class="main_1 grid_8 field" data-field='main_1'>
        <div class='module'>
        <div class="content content-editor" data-id='1' data-module='content' contenteditable='true'>
            <h1>Heading 1</h1><p>"Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

        </div>
        </div>
            <div class='module'>
        <div class="content content-editor" data-id='4' data-module='content' contenteditable='true'>
            <h4>Yet another content</h4><p>This is yet another contentblock!</p>
        </div>
        </div>
    </section>
    <aside class="aside_1 grid_4 field" data-field='aside_1'>
        <div class='module'>
        <div class="content content-editor" data-id='2' data-module='content' contenteditable='true'>
            <h2>Aside Content</h2><p>Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt explicabo.</p>
        </div>
        </div>
    </aside>
    <div class="x-clear"></div>
</div>

And here is the js:

    $(document).ready(function() {
    /*
    * - on hoover, we display the panel
    */
    $( ".content-editor" ).mouseenter(onMouseIn);
    $( ".edit-wrap" ).live("mouseleave", onMouseOut);

    /*
    * - on click/focus, we set it as active
    */
    $( ".content-editor" ).focus(onFocus);
    $( ".content-editor" ).blur(onLostFocus);
});


/*
* - functions
*/
function onMouseIn() {
    if ($(this).attr('data-active') != "true" && !dragging) {
        console.log("wasnt active: " + $(this).attr('data-active'));
        makeActive($(this));
    } else {
        console.log("was active: " + $(this).data('id') + " - act: " + $(this).attr('data-active'));
    }
}
function onMouseOut() {
    console.log("mouse out");
    if ($(this).find(".content").attr('data-editing') != "true" && $(this).find(".content").attr('data-dragging') != "true") {
        console.log("no edit, no dragging");
        removeActive($(this).find(".content"));
    } else {
        console.log("edit: " + $(this).find(".content").attr("data-editing"));
        console.log("dragging: " + $(this).find(".content").attr("data-draging"));
    }
}
function onFocus() {
    $(this).attr('data-editing', 'true');
}
function onLostFocus() {
    console.log("lost focus: " + $(this).data('id'));
}
function makeActive($this) {
    $this.attr('data-active', "true");

    $this.wrap("<div class='edit-wrap'>");
    var $parent = $this.parent(".edit-wrap");

    $parent.prepend("<div class='edit-head'>&raquo; Content ( Quick Edit )</div>");
    $parent.append(editMenu);
}
function removeActive($this) {
    $this.parent(".edit-wrap").find(".edit-head").remove();
    $this.parent(".edit-wrap").find(".edit-menu").remove();

    $this.unwrap(".edit-wrap");
    $this.attr('data-active', "false");
}


/*
* - html
*/
var editMenu = "<div class='edit-menu'>"+
        "<a href='#' class='btn openEditor'>Öppna Editor</a>"+
        "<a href='#' class='btn quicksave'>Snabspara</a>"+
        "</div>";

and:

    var dragging = false;

$(document).ready(function() {
    /*
    $( ".edit-head" ).live("mouseover", function() {
        $(this).parent(".edit-wrap").draggable({
            handle: ".edit-head",
            revert: 'invalid'
        }); 
    });

    $( ".edit-wrap" ).live("dragstart", function() {
        $(this).find(".content").attr("data-dragging", "true");
    });
    $( ".edit-wrap" ).live("dragstop", function() {
        $(this).find(".content").attr("data-dragging", "false");
        removeActive($(this).find(".content"));
    });
    */

    $( ".field" ).sortable({
        start: function(e, ui) {
            ui.placeholder.height(ui.item.height());
            $(this).find(".content").attr("data-dragging", "true");
            dragging = true;

            $(".field").addClass("target");

        },
        stop: function() {
            $(this).find(".content").attr("data-dragging", "false");
            dragging = false;

            $(".field").removeClass("target");
        },
        connectWith: '.field',
        placeholder: "drop-placeholder",
        dropOnEmpty: true,
        handle: ".edit-head",

        update: function(e, ui) {
            var $this   = ui.item;
            var $sender = ui.sender;

            if ($sender) {
                //vi bytte field
                console.log("bytte");
            } else {
                console.log("bytte inte");
            }
            console.log("change: " + $this + " from: " + $sender);
        }
    });
});

Look for typos:

attr("data-draging") 

and somewhere else in your code

attr("data-dragging") 

However as said, use:

data("dragging")
