one simple question about list

[manish khamar]

hi

I have one complex problem.

I parse json using ajax request and get response properly.
then show it in list as below:

code:
-------------------------------------------------------------------------------------------
Ext.Ajax.request({
url:'trial.json',
method: 'post',
success: function(response){
recdata = Ext.decode(response.responseText);
Ext.regModel('User', { fields: ['address']
});
var c = new Ext.data.Store({
model: 'User',
autoLoad: true,
data: [recdata],
});
var myTpl = new Ext.XTemplate(
'<tpl for="."><div class="user"><div>{address}</div><div class="pic"><img src="{[values.picture[0].url]}" ></div></div></tpl>'
);

var list = new Ext.List({ fullscreen: true,
itemTpl :myTpl,
store : c
});
-------------------------------------------------------------------------------------------------
I can list all data properly from json means address and image both.

But now problem is that in my json some url tag do not consist any image string so i can not display that image.So I want to display some defualt image there.But i have no idea how i can do that.
so pls help me to solv it.
