Subject [jira] [Commented] (CB-3530) PhoneGap app crashes on iOS with error "CDVWebViewDelegate: Navigation started when state=1"
Date Tue, 18 Jun 2013 02:42:19 GMT

    [ https://issues.apache.org/jira/browse/CB-3530?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13686317#comment-13686317

Farhad Farzaneh commented on CB-3530:
-------------------------------------

I am having same problem on 2.7.0 on iOS with jqueryMobile.  It seems that if you navigate
from one part of a document to another using jqueryMobile, it triggers a loadPage() method.
 This in turn triggers shouldStartLoadWithRequest: in the CDVWebViewDelegate, which bumps
the state from STATE_IDLE to STATE_WAITING_FOR_LOAD_START.  However, because the page is already
loaded, and doesn't really require further loading, no other state events are triggered, so
the _state gets stuck waiting for a load start, and you'll keep getting this message.

I'm not familiar enough with the source, but it seems we should be able to know that that
we're already on the page, and change the state transitioning logic accordingly if we're just
moving from one hashtagged ref to another.

> I have a PhoneGap app on iOS which was working fine with PhoneGap 2.3.0 but crashes with
2.7.0 with the following error:
> 2013-05-02 10:08:13.214 App[8896:c07] CDVWebViewDelegate: Navigation started when state=1
> 2013-05-02 10:08:13.215 App[8896:c07] Failed to load webpage with error: (null)
> The problem is:
> CDVWebViewDelegate.m: shouldStartLoadWithRequest() function: In switch case, default:
error code is being passed as nil
> and in CDVInAppBrowser.m: didFailLoadWithError() function, error.localizedDescription
is being referenced, which causes a crash as error object is nil. 
> For now, i added a check in the above function to put default values for error code if
the error object is nil. I hope this crash is fixed in the next PhoneGap release.
