    <p>So i recently added Kinetic.JS <strong>v4.6.0</strong> to my app, and tested out a simple rectangle drag and drop. </p> <p>Works fine on the web browser, but as soon as i use it on a mobile, it bugs out and leaves a ghost of the rectangle after dragging.</p> <p>I'm basically using the same script as the <a href="http://www.html5canvastutorials.com/kineticjs/html5-canvas-mobile-events/" rel="nofollow">demo</a>, without the touchStart/touchEnd events, i'm also using JQuery 1.9.1 and JQueryMobile-1.3.2. </p> <p>How can i get rid of this effect, i've tried clearing the layer on touchStart and drawing the stage again on touch End but the ghost stays there.</p> <p><strong>Edit</strong> My device is a Galaxy S2 running 4.2.2 and the ghosting happens, but the app works fine on the Ipad.</p> <p><strong>/index.JS</strong></p> <pre><code>$( window ).on( "pageinit", function ( event ) { stage = new Kinetic.Stage( { container: "container", width: 500, height: 500 } ); MapLayer = new Kinetic.Layer() var Rect = new Kinetic.Rect( { x: 0, y: 0, width: 100, height: 50, fill: 'green', stroke: 'black', strokeWidth: 4, draggable: true } ); MapLayer.add( Rect ); stage.add( MapLayer ); </code></pre> <p><strong>Index.HTML</strong></p> <pre><code>&lt;script src="js/jquery-1.9.1.min.js"&gt;&lt;/script&gt; &lt;script src="js/jquery.mobile-1.3.2.min.js"&gt;&lt;/script&gt; &lt;script src="js/kinetic-v4.6.0.min.js"&gt;&lt;/script&gt; &lt;script src="js/index.js"&gt;&lt;/script&gt; &lt;title&gt;Mobile OneStop&lt;/title&gt; &lt;div data-role="page"&gt; &lt;div data-role="content"&gt; &lt;div id="container"&gt; &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>( I might do a badly drawn paint image to show this off if people do not understand) </p> <p><strong>Edit</strong> <a href="http://imgur.com/a/HlNxj#0" rel="nofollow">http://imgur.com/a/HlNxj#0</a> - Ive changed a lot of the code since posting this, but the issue still remains.</p>

    1. CODid you try on multiple devices? Also, do you receive the ghosting on one his demos? Canvas animation uses a lot of CPU and choppiness may vary.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
