it disturbs the main database of my main application.
Iam using the database in my main application. When i open a page in the inapp
browser for one of the menus in main application and close using the done
button. After coming back to the main application, all the pages which are
database driven are not working as i get 'no such table' error. So i cannot use
local storage here. Please guide me.

> Created an app where on the first page, user creates and enters values into a
> table, upon success, he is sent to a second page which Contains a link to
> Google using Childbrowser as well as a button to show content of database.
> If user clicks button to show content of database immediately he gets to page
> 2, the result is as expected but if he should click button to childbrowser,
> when he closes and clicks the result button, it states table does not exist
> returning *Error: Undefined*
> However, if user goes back to page one and recreates the whole table as well
> as enter the values, then clicks childbrowser, return and click return
> button, it starts working.
> All subsequent visits also work provided you do not clear data/cache.
