Subject [jira] [Commented] (CB-1535) LocalStorage is not saved after first App launch on iOS 6
Date Tue, 25 Sep 2012 16:26:08 GMT

    [ https://issues.apache.org/jira/browse/CB-1535?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13462915#comment-13462915
] 

Christian Kuetbach commented on CB-1535:
----------------------------------------

I think I have an idea, why this happens:

The first time, the app loads the localStorage is not persistent. The flag will be set by
cordova. The localStorage is loaded from the cache folder. Everything will be stored in the
files located in that folder.

>From the second time forward the localStorage is loaded from another (persitent) folder.
All changes are stored there.

> 1. Save a value in window.localStorage after a fresh install of the App in Simulator
or iOS Device.
> 2. Stop the App while running in Background.
> 3. Restart the App and Restoring the value from window.localStorage is not possible (Error)
> 4. Save a new value in window.localStorage
> 5. Stop the App while running in Background.
> 6. Restart the App and now you can restore the value (Everything runs fine from now on)
> To reproduce create a sample project with the "create" script.
> Put this Javascript into index.html or use the attached index.html.
> The Parameter BackupWebStorage is not changed.
> BackupWebStorage=YES
