    <p>I am using Titanium and running the emulator on iOS7. I am trying to get a card like flipping animation. I have it half way working. It will current flip from <code>front</code> to <code>back</code>, but as soon as I click it again, the app crashes and my console isn't showing anything.</p> <p>The docs say:</p> <p><code>The new view being transitioned to should NOT be a child of another view or of the animating view.</code></p> <p>Maybe I am understanding that wrong because I cannot seem to make this work. My code so far is:</p> <pre><code>var win = Ti.UI.currentWindow; var noThumbColors = ['#555555','#cccccc']; var noThumbColors2 = ['#ff0000','#000']; var views = []; var fronts = []; var backs = []; for (var i = 0; i &lt; 1; i++) { fronts[i] = Ti.UI.createView({ id:i, name:"front", width:150, height:150, backgroundGradient:{ type: 'linear', startPoint: { x: '0%', y: '0%' }, endPoint: { x: '0%', y: '100%' }, colors: [ { color: noThumbColors[0], offset: 0.0}, { color: noThumbColors[1], offset: 1.0 } ], }, currentAngle: 10 }); backs[i] = Ti.UI.createView({ id:i, name:"back", width:150, height:150, backgroundGradient:{ type: 'linear', startPoint: { x: '0%', y: '0%' }, endPoint: { x: '0%', y: '100%' }, colors: [ { color: noThumbColors2[1], offset: 0.0}, { color: noThumbColors2[0], offset: 1.0 } ], }, currentAngle: 10 }); win.add(backs[i]); win.add(fronts[i]); fronts[i].addEventListener('click', function(e) { log(e.source.name); t = Ti.UI.iPhone.AnimationStyle.FLIP_FROM_LEFT; e.source.animate({view:backs[e.source.id],transition:t}); }); backs[i].addEventListener('click', function(e) { log(e.source.name); t = Ti.UI.iPhone.AnimationStyle.FLIP_FROM_RIGHT; e.source.animate({view:fronts[e.source.id],transition:t}); }); } function log(msg) { Ti.API.info(msg); } </code></pre> <h2><strong>The finished working code (will produce 3 squares that will flip back and forth independently):</strong></h2> <pre><code>var win = Ti.UI.currentWindow; var noThumbColors = ['#555555','#cccccc']; var noThumbColors2 = ['#ff0000','#000']; var containers = []; var fronts = []; var backs = []; for (var i = 0; i &lt; 3; i++) { containers[i] = Ti.UI.createView({ top:50 + (i * 155), width:150, height:150 }); fronts[i] = Ti.UI.createView({ id:i, name:"front", width:150, height:150, backgroundGradient:{ type: 'linear', startPoint: { x: '0%', y: '0%' }, endPoint: { x: '0%', y: '100%' }, colors: [ { color: noThumbColors[0], offset: 0.0}, { color: noThumbColors[1], offset: 1.0 } ], }, currentAngle: 10 }); backs[i] = Ti.UI.createView({ id:i, name:"back", width:150, height:150, backgroundGradient:{ type: 'linear', startPoint: { x: '0%', y: '0%' }, endPoint: { x: '0%', y: '100%' }, colors: [ { color: noThumbColors2[1], offset: 0.0}, { color: noThumbColors2[0], offset: 1.0 } ], }, currentAngle: 10 }); containers[i].add(backs[i]); containers[i].add(fronts[i]); win.add(containers[i]); } win.addEventListener('click', function(e) { if (e.source.name === "front") { containers[e.source.id].animate({view:backs[e.source.id],transition:Ti.UI.iPhone.AnimationStyle.FLIP_FROM_LEFT}); } else if (e.source.name === "back") { containers[e.source.id].animate({view:fronts[e.source.id],transition:Ti.UI.iPhone.AnimationStyle.FLIP_FROM_RIGHT}); } }); function log(msg) { Ti.API.info(msg); } </code></pre>

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.
