[jira] [Commented] (CB-258) iFrame parent is null on Android 4.0+
[ https://issues.apache.org/jira/browse/CB-258?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13226884#comment-13226884 ]
David Marques commented on CB-258:
----------------------------------
Hello Jared,
There is an issue in the webkit engine that prevents this to work on local files (http://code.google.com/p/chromium/issues/detail?id=47416)
I would suggest trying to avoid that kind of intra frame interaction for web apps running on top of phonegap for now.
Hope it helps,
David
