Ext.List Only Rendering on Orientation Change - sencha-touch

Question

Ext.List and Ext.Panel Code Code
Ext.namespace('Envato.AudioJungle.Previewer');
var lastItemClicked = null; // Stores the last 'play' or 'pause' item clicked on
Envato.AudioJungle.Previewer.audioPreview = new Ext.Audio({}); // Blank audio player used to preview the items

var selectedItem = self.getRecord(item);
var tapTarget = e.getTarget(); // Stores what we clicked on
if(tapTarget.innerHTML == 'Play') { // We clicked on a 'Play button'
if(lastItemClicked && lastItemClicked.innerHTML == 'Pause') { // Another item is currently playing
lastItemClicked.innerHTML = 'Play'; // Switch the button to 'Play'
}
lastItemClicked = tapTarget; // Store the currently clicked item as the last clicked item
lastItemClicked.innerHTML = 'Pause'; // Set the button we clicked on to 'Pause'
if(Envato.AudioJungle.Previewer.audioPreview.url) { // Check to see that the audio previewer is not empty
Envato.AudioJungle.Previewer.audioPreview.pause(); // Pause it
}
// Reset the audio previewer to play the item clicked
Envato.AudioJungle.Previewer.audioPreview = new Ext.Audio({
id: 'audioPreview',

// Play the audio
Envato.AudioJungle.Previewer.audioPreview.play();

} else {
Ext.Msg.confirm("Audio Jungle", "View this item at AudioJungle.com?", function(btn) {
if(btn == 'yes') {
location.href = selectedItem.get('url');
}
});
}
}
}
});
Envato.AudioJungle.Previewer.optionToolbar = {
dock: 'top',
xtype: 'toolbar',

};
Envato.AudioJungle.Previewer.displayPanel = new Ext.Panel({

Store Code
var popularItemFields = [{
name: 'preview_url',
type: 'string'
},{
name: 'sales',
type: 'integer'
},{
name: 'user',
type: 'string'
},{
name: 'cost',
type: 'float'
},{
name: 'url',
type: 'string'
},{

type: 'date',

type: 'string'
},{

type: 'string'
}];
Ext.regModel('PopularItem', {
fields: popularItemFields
});
Envato.Stores.popularItemsStore = new Ext.data.JsonStore({
sorters: 'item',
model: 'PopularItem',
storeId: 'popularItemStore',
autoLoad: true,
proxy: {
type: 'ajax',
url: 'php/scripts/envato.php',
extraParams: {
site: 'audiojungle'
},
reader: {
type: 'json',
root: 'root',
idProperty: 'id'
}
},
getGroupString: function(record) {
return record.get('item')[0];
}
});
Main.js code
Ext.namespace('Envato', 'Envato.AudioJungle', 'Envato.AudioJungle.Previewer', 'Envato.Stores');
Ext.setup({
onReady: function() {
Envato.AudioJungle.Previewer.displayPanel.render(Ext.getBody()).doComponentLayout();
}
})
on mobile devices (iphone and ipad), the toolbar will render just fine but the list won't render until I change the device's orientation.
On chrome, it renders just fine. Does anyone see anything glaring that would cause this?

Answer 1

By declaring the panel as fullscreen: true, it will automatically render to the document body on creation (ie. before onReady).
Ext.setup({
onReady: function(){
Ext.regModel('Item', {
fields: ['text']
});
new Ext.Panel({
fullscreen: true,
layout: 'fit',
dockedItems: [{
xtype: 'toolbar',
items: {
text: 'I am a button'
}
}],
items: {
xtype: 'list',
itemTpl: '{text}',
store: new Ext.data.Store({
model: 'Item',
data: [{
text: 'Foo'
}]
})
}
});
}
});
