localStorage on wp8 error - html

Question

I have a WP8 HTML/JS app and I need to save some simple data on the local storage. It should be something very easy, but it is giving my a headache already.
I tried to call the localStorage in many different ways but it doesn't work. The error message I get is:
The system cannot find the file specified.
The strange part, is that the sessionStorage seems to be fine. At least I don't get any error using that object.
Additional info:
- The ways I called localStorage are: localStorage.setItem(), window['localStorage'], window.localStorage, etc. they all say the same message.
- I am developing a Windows Phone HTML app OS8.
- The method I call the localStorage is in $('#channels').bind('pagebeforeshow', function (e, data) {...}
- The only references in the project are .Net for Windows Phone and Windows Phone.
- Some of the js libs I included are jQuery, jQuery mobile and ko.
- I am testing on both WP8 device and Emulator
I prefer not to use phoneGap and any other known db for devices, since I wouldn't like to involve interaction with the native code just to make the call to fetch and save some data.
UPDATE 1:
After thefrontender comment, I investigated one by one my js refs. The problem appear when I add the jqm 1.3 min.
All js are bundled with my app. Any other suggestions?
$(function () {
try {
localStorage.setItem('aaa', 123);
alert(localStorage.aaa);
}
catch (err) { alert(err.message) }
});

Answer 1

And if you replace
alert(localStorage.aaa);
with
alert(localStorage.getItem('aaa');

I got my answer form jQuery official forum after all.
