Why ListView gives o is undefined error with store.loadData?

[nagarajan.bose]

Hi,
We are extending a listview and it works fine when I load the data directly from store. However I have a situation, where I need to make an AJAX call and load the data using store.loadData(Ext.decode(response.Text)), it fails with an error "o is undefined".

Working Code:


SearchResults = Ext.extend(Ext.list.ListView, {
id : 'lvresults',
singleSelect : true,
emptyText : '<div style="padding:5px;">No results to display</div>',
title : 'Search Results',
reserveScrollOffset : true,
hideHeaders : true,
fields : ['id', {
name : 'gdate',
type : 'date',
dateFormat : 'c'
}],
columns : [{
dataIndex : 'gdate',
xtype : 'datecolumn',
format : 'D M d Y, G:i T'
}],
initComponent : function() {
this.tpl = new Ext.XTemplate(
'<tpl for="rows">',
'<dl class="x-grid3-row {[xindex % 2 === 0 ? "" : "x-grid3-row-alt"]}">',
'<tpl for="parent.columns">',
'<dt style="width:{[values.width*100]}%;text-align:{align};">',
'<em unselectable="on"<tpl if="cls">class="{cls}"</tpl>>{[values.tpl.apply(parent)]}',
'</em></dt></tpl><div class="x-clear"></div></dl></tpl>')
this.store = new Ext.data.JsonStore({
url:"/data/json/mmmmm/xxxxx.json",
root : 'rows',
idProperty : 'id',
fields : this.fields
})
SearchResults.superclass.initComponent.apply(this);
},
listeners : {
render : function() {
this.bindStore(this.store);
this.store.load();
}
}// eo listeners
});
Ext.reg(logviewresults', SearchResults);


Fails to load using the below code:


Ext.Ajax.request({
url:"/data/json/mmmmm/xxxxx.json",
success : function(response) {
Ext.getCmp("lvresults").store.loadData(Ext.decode(response.Text))
//Ext.getCmp("lvresults").bindStore(Ext.getCmp("lvresults").store) -->Tried this too... no use
},
failure : function(response){
//TODO: Handle failures here
}
})


Can any one point us where we are failing.

Thanks for your time and help.

What is response.Text? Do you mean response.responseText?

[mitchellsimoens]

And why are you using Ext.Ajax to load a Store when you can use JsonStore to do it all?

[nagarajan.bose]

Thanks Skirtle and Mitchellsimoens for looking into my problem.

Skirtle: I inspected response.responseText and it contains JSON data. So I am clear here I am not doing anything wrong.

Mitchellsimoens: I have a requirement where I will be building the URL dynamically and make a call. Hence I am using AJAX to load the data and then to refill the store.

If the data is the same, you can use same store for multiple grids. Only problem is if you are going to filter one grid. I would still use a store and sync between the two.

@nagarajan.bose, in the code you posted you're using response.Text, not response.responseText.
