A weird error occurs in ui.js[dynamic], saying Unable to get value of the property 'offset': object is null or undefined in this function
_groupFromOffset: function (offset) {
this._updateOffsets();
return offset < this._getGroup(0).offset ? 0 : this._site.groups.groupFromOffset(offset);
},
I was trying clear the list variable (WinJS.Binding.List();) in data.js file, once i got the data from service. If i don't
do that, i'm not getting that error, So i'm doing something wrong in clearing the list. and repopulating. Here is the code snippet.
var list = new WinJS.Binding.List();
function getHomePageData() {
list.forEach(function (item) {
list.dataSource.remove(item.key);
});
return new WinJS.Promise(
function (c, e, p) {
WinJS.xhr({ url: "URl" }).then(
function (req) {
if (req.readyState == 4 && req.status == 200) {
var responseXML = req.responseXML.getElementsByTagName('HomePage');
for (var i = 0; i < responseXML.length; i++) {
try {
//list._currentKey = i;
list.push({
group: {
key: keydata
title: titledata
},
});
}
catch (exception) {
}
}
c({
results: list
});
}
},
function (req) {
e(req.status);
},
function (req) {
p(req);
});
});
}
So basically what i'm trying to do is, every time it comes in i want to remove the existing and push the latest data.
but its all working fine but when i navigate to next page and while coming back to landing page
i'm getting that error!! Can some one help me in this?
