Html5 localStorage in Folio, InDesign 5.5

Question

Hi,
for a customer we have build a presentation in InDesign CS5.5 as Folio which works fine.
And we made a small htm5 page with a formular which stores some information via “localStorage.setItem()”. In any browser that works fine too.
But when we import the html into the folio, an error occurred. It seems, that the localStorage is the point of failure.
Is there any thing that we can do to bring the html to work inside the folio?

There´s no AIR in iPad. It uses webkit engine to run html-content inside native applications. And there are some restrictions, all the functions you can use with normal browsers are not supported there. You should find webkit´s specifications from Apple´s developer portal.
I don´t know what kind of data you want to save, but one possible way to do it is use iPad´s built in database. It´s quite easy to use and you can store data from html-page, also from one you have placed inside folio (I used to make nice little yellow sticky note widget by using that) Users could create new sticky notes and write some text into them and everything was stored into iPad´s database. Next time they visited same folio, all the data was pulled back to sticky notes automatically... I used a sticy notes code from apple´s html5 showreel with small modifications.
You will find original code from here http://developer.apple.com/safaridemos/sticky-notes.php
Open notes.js to see how iPad´s local database is instantiated.
ps. I understand that you have very good reasons to use DPS and folios, I just want to clarify to other possible readers that html5 web-apps eDocker produces are cached with html5 local storage manifest and they are also running in offline mode....=)
