Question about XTemplate usage in a view config

[parky128]

Hi,

Is it possible to get a reference to the application instance from a member function of an XTemplate in a view config? Sorry, thats quite a mouthful there! Here is some code:


Ext.define('PinpointersTouch.view.UnitList', {
extend: 'Ext.List',
xtype: 'unitslist',
config: {
fullscreen: true,
itemTpl: new Ext.XTemplate(
'<ul id="unitList">',
'<tpl for=".">',
'<li>',
'<table width="100%" cellspacing="0">',
'<tr>',
'<td style="width:30px; text-align:center">{[this.getUnitIcon(values.id)]}</td>',
'<td valign="middle"> - {UnitName}</td>',
'</tr>',
'</table>',
'</li>',
'</tpl>',
'</ul>',
{
getUnitIcon: function(untID) {
//var iconNum = this.application.getTrackingListStore().getById(untID).data.MapIcon;

//TO Do: Can I get a reference to the application instance from in here???
}
}),
store: 'CurrentGrid'
}
});


I need to look up some values in another store in my application based on a value being passed into the XTemplate member function.

Yes and no.

By default, the application instance isn't cached anymore so in your launch method you can cache it on your namespace:


Ext.application({
name : 'MyApp',

launch : function() {
MyApp.app = this;
}
});

Now anywhere in your code you can access the application instance from MyApp.app.

Which is a bug in PR2, and will be fixed before GA. But for now, that fixes it. :)

Couldn't you also use Ext.getStore() and then filter it by the id property, or use findExact() if the id is unique? Or am I way off base.../:)
