I have a grid that I’m trying to populate from an XmlStore, which is populated from an Xml String. So far, the store appears to be load the XML just fine, but I cannot get the grid to load the store. (i.e. grid.getStore().getCount() is always 0.
// create the Data Stores for use by the grid
Ext.define('InterfaceModel', {
extend: 'Ext.data.Model',
fields: [
{ name: 'id', mapping: 'id' },
{ name: 'InterfaceName', mapping: 'InterfaceName' },
{ name: 'TX_OCTETS', mapping: 'TX_OCTETS' },
{ name: 'TX_BAD_OCTETS', mapping: 'TX_BAD_OCTETS' },
{ name: 'TX_FRM', mapping: 'TX_FRM' },
{ name: 'TX_BAD_FRM', mapping: 'TX_BAD_FRM' },
{ name: 'TX_MCAST', mapping: 'TX_MCAST' },
{ name: 'TX_BCAST', mapping: 'TX_BCAST' },
{ name: 'TX_PAUSE', mapping: 'TX_PAUSE' }
],
idProperty: 'id'
});
My XML is as follows:
var gridData = '<?xml version="1.0" encoding="UTF-8"?> <Interfaces> <Interface> <id>1</id> <InterfaceName>GMAC1</InterfaceName> <TX_OCTETS>123234</TX_OCTETS> <TX_BAD_OCTETS>234</TX_BAD_OCTETS> <TX_FRM>234234</TX_FRM> <TX_BAD_FRM>2341</TX_BAD_FRM> <TX_MCAST>23</TX_MCAST> <TX_BCAST>56</TX_BCAST> <TX_PAUSE>8</TX_PAUSE></Interface> <Interface> <id>2</id> <InterfaceName>GMAC2</InterfaceName> <TX_OCTETS>123234</TX_OCTETS> <TX_BAD_OCTETS>234</TX_BAD_OCTETS> <TX_FRM>234234</TX_FRM> <TX_BAD_FRM>2341</TX_BAD_FRM> <TX_MCAST>23</TX_MCAST> <TX_BCAST>56</TX_BCAST> <TX_PAUSE>8</TX_PAUSE></Interface></Interfaces>';
var gridDataXml = (new DOMParser()).parseFromString(gridData,'text/xml');
console.log ('xml', gridDataXml); // everything looks fine
I then define my store using a memory proxy XML reader:
var eioaGridStore = new Ext.data.XmlStore({
model: 'InterfaceModel',
autoLoad: true,
proxy: {
type: 'memory',
reader: {
type: 'xml',
root: 'Interfaces',
record: 'Interface',
idProperty: 'id'
}
}
});
And then load the parsed XML DOM into the store:
eioaGridStore.loadRawData(gridDataXml);
If I getCount() on the store, it properly responds with 2.
Viewing the store from the Web Inspector shows 2 arrays (that I want to be rows in my grid) (pardon the formatting)

My grid component is as follows:
createGrid: function () {
var me = this;
return {
id: 'eioaGrid',
xtype: 'grid',
border: true,
store: this.eioaGridStore,
columns: [{
header: 'Interface',
dataIndex: 'InterfaceName',
align: 'center',
sortable: true,
tooltip: 'Axxia Interface'
}, {
text: 'OCTETS',
sortable: false,
width: 100,
tooltip: 'Total number of octets in all frames.',
columns: [{
header: 'TX',
width: 50,
align: 'center',
sortable: true,
dataIndex: 'TX_OCTETS',
tooltip: 'Transmitted'
}]
}, {
text: 'BAD OCTETS',
sortable: false,
width: 100,
tooltip: 'Total number of octets in all bad frames.',
columns: [{
header: 'TX',
width: 50,
align: 'center',
sortable: true,
dataIndex: 'TX_BAD_OCTETS',
tooltip: 'Transmitted'
}]
}, {
text: 'FRAMES',
sortable: false,
width: 100,
tooltip: 'Total number of frames.',
columns: [{
header: 'TX',
width: 50,
align: 'center',
sortable: true,
dataIndex: 'TX_FRM',

}]
}, {
text: 'BAD FRAMES',
sortable: false,
width: 100,
tooltip: 'Total number of bad frames.',
columns: [{
header: 'TX',
width: 50,
align: 'center',
sortable: true,
dataIndex: 'TX_BAD_FRM',
tooltip: 'Transmitted'
}]
}, {
text: 'MULTICAST',
sortable: false,
width: 100,
tooltip: 'Multicast Frames: good non-pause frames with a multicast destination address which is not the broadcast address.',
columns: [{
header: 'TX',
width: 50,
align: 'center',
sortable: true,
dataIndex: 'TX_MCAST',
tooltip: 'Transmitted'
}]
}, {
text: 'BROADCAST',
sortable: false,
width: 100,
tooltip: 'Broadcast Frames: good frames with the broadcast destination address.',
columns: [{
header: 'TX',
width: 50,
align: 'center',
sortable: true,
dataIndex: 'TX_BCAST',
tooltip: 'Transmitted'
}]
}, {
text: 'PAUSE',
sortable: false,
width: 100,
tooltip: 'Pause Frames: pause frames internally generated by the MAC.',
columns: [{
header: 'TX',
width: 50,
align: 'center',
sortable: true,
dataIndex: 'TX_PAUSE',
tooltip: 'Transmitted'
}]
}]
};
}
Later, I then getCount() via the grid’s store and it comes back as empty.
console.log('grid store count', Ext.getCmp('eioaGrid').store.getCount());
Any ideas? Been stumped for a couple of days now and I’m going mad! thanks.
I just found it… my reference to this.eioaGridStore when setting the grid store: was not in scope (was undefined)… everything now working.
