Just confirming this occurs in the main webview as well as the inapp browser. It seems to be related to having a hashtag in the URL.

wow, thanks for the info. Apparently, the error "CDVWebViewDelegate: Navigation started when state=1" is only coming with 2.7.0. After getting this error, we see "Load error" in the InAppBrowser status bar. I hope this gets fixed in the next release.

Hi all, what is the window.open code to replicate this?

var ref = window.open(url, '_blank', 'location=yes');
The app doesn't crash immediately. Once i close the child browser and try to do anything in the main app, it crashes

Please provide a url that this can be replicated on, since I can't repro this

Try with this URL: en.wikipedia.org/wiki/Hashtag
Click on different items in the TOC like Origin, Style etc. if you don't get the error the 1st time after clicking on an item, then scroll to the top of this URL page and click on another link, eventually you will get the following error:

"CDVWebViewDelegate: Navigation started when state=1"
"webView: didFailLoadWithError - (null)

• • • WebKit discarded an uncaught exception in the webView:decidePolicyForNavigationAction:request:frame:decisionListener: delegate: <NSInvalidArgumentException> *** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[3]

I can reproduce this even on the iPad simulator. After this error, all links stop working in the same instance of InAppBrowser and i get 3 lines of error mentioned above.

Thank you! I'll verify and fix tomorrow.

Thanks! that sounds good. Will this fix be included in 2.8.0?
Can you please also look at this issue: https://issues.apache.org/jira/browse/CB-3531

Still couldn't repro, but found the culprit I think (thanks for the clues in the description): https://github.com/apache/cordova-ios/blob/7e0a32892a540295e7de5da6a4832dfdaf337ac0/CordovaLib/Classes/CDVWebViewDelegate.m#L200

didFailLoadWithError code always assumes that the NSError passed in is not nil. The fix is not to pass in nil there but create a default one.

CB-3530 PhoneGap app crashes on iOS with error "CDVWebViewDelegate: Navigation started when state=1"

CB-3530 PhoneGap app crashes on iOS with error "CDVWebViewDelegate: Navigation started when state=1"

That's great! Thanks a lot!

Can you please check https://issues.apache.org/jira/browse/CB-3576 and https://issues.apache.org/jira/browse/CB-3531?
I think CB-3576 can be fixed easily. It's really a problem that we can't access locally signed https URLs in InAppBrowser.

Thanks for the fix! when can we expect 2.8.0 with this fix?

I get this Error with Phonegap 2.8.0 The App works on Android fine, but on iOS I get this error.

I tested this today with 2.8.0 and the issue is not entirely fixed. The navigation doesn't break now and the app doesn't crash (compared to 2.7.0) but the error "CDVWebViewDelegate: Navigation started when state=1" can still be seen on the XCode debug terminal and the InAppBrowser tool bar displays a "Load Error" so it's very misleading for the user. Here's the complete error trace:

"CDVWebViewDelegate: Navigation started when state=1"
"webView:didFailLoadWithError - CDVWebViewDelegate: Navigation started when state=1"

It seems that the fix only handled nil being passed as error code but didn't handle the reason why "CDVWebViewDelegate: Navigation started when state=1" error is coming

The issue is not entirely fixed. Please check my latest comment for more details.

I'm getting a very similar behavior on 2.8.0 in iOS to what Montyleena described.
The complete error trace is:

"CDVWebViewDelegate: Navigation started when state=1"
"Failed to load webpage with error: CDVWebViewDelegate: Navigation started when state=1"

What could be done to fix this?

Ok, I'll take a look again but the author of the state machine code is away so it may take some time for me to get familiar. But does anything actually fail? (besides the error message). Anything on the loaded webpage that is not working?

@Shazron, there is no issue with the functionality after getting this error but the InAppBrowser tool bar displays the message: "Load Error" so it's very misleading for the user, so this does needs to be fixed. This issue wasn't coming in 2.4.0 on iOS (i upgraded from 2.4.0 to 2.7.0 and now 2.8.0)

Not sure if it's related but I'm experiencing a "blinking" effect when transitioning within a single page app and using href="#pagetwo" which I didn't notice this on 2.6.0.

Could it be relevant?
If not, do you happen to know how I can deal with it?

Fredy Levin: Is your code fully working with this "blinking"? I do have the same problem. The console log shows twice the error message every time I change page and using anchors href="#pagetwo". I'm using 2.8.0.

"CDVWebViewDelegate: Navigation started when state=1"
"Failed to load webpage with error: CDVWebViewDelegate: Navigation started when state=1"

Monica, the code seems to be working but the blinking thing obviously affects user experience.
I'm getting the same 2 error messages as you are but only from the 2nd transition, the first one doesn't generate any errors.

I solved the problem for my issue i used jquery mobile but dont usecthis then you get the error too. $.mobile.changePage( "../resources/confirm.html"). You have to use it in this way
$.mobile.changePage( '../resources/confirm.html'). Now the works on ios fine.

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 solved the problem for my use case by inserting the following code in CDVWebViewDelegate.m in method - (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType

[line 166 in my version]

//    We're going to check if this URL is simply moving from one part of a document to another.  If it is, we should not load it again 
    if ( webView && webView.request && webView.request.URL ) {
        NSString *prevUrl, *requestUrl;
        prevUrl = webView.request.URL.absoluteString;

        NSString *urlFragment =@"#";
        if (webView.request.URL.fragment)
            urlFragment = [urlFragment stringByAppendingString:webView.request.URL.fragment];
        NSRange range = [prevUrl rangeOfString:urlFragment];
        prevUrl = [prevUrl substringToIndex:range.location];
        
        urlFragment = @"#";
        if ( request.URL.fragment )
            urlFragment = [urlFragment stringByAppendingString:request.URL.fragment];
        requestUrl = [request.URL.absoluteString substringToIndex:range.location];
        
        //  Actually not sure if this should return YES or NO - NO works for my use case
        if ( [prevUrl isEqualToString:requestUrl] )
            return NO;
    }

I think Farhad Farzaneh's proposed solution is the answer. Farhad, if you have a pull request, that would be great so we can credit you (and make changes as appropriate).

If not I could adapt it, add tests, and put it in for you.

I don't have a pull request, and am actually not familiar enough with the code to understand the unintended consequences of my fix. One thought is that returning NO above could mess up the browsing history if someone is counting on that. Will try to test and report back.

Also, not being familiar with objective-C, I looked to see if I could add tests by adapting from existing tests but didn't see anything appropriate. So please feel free to adapt and add tests.

CB-3530 PhoneGap app crashes on iOS with error "CDVWebViewDelegate: Navigation started when state=1" (for navigation to an anchor on the same page)

I have upgraded to Phonegap 2.9.0. The error was showing twice in 2.8.0. Now in 2.9.0 it shows only once under same circumstances. Is something else causing it? Should I do something else?

Monica Magallanes what url triggers this? Before this line: https://github.com/apache/cordova-ios/blob/master/CordovaLib/Classes/CDVWebViewDelegate.m#L240

Can you add this code and report if it gets printed out when you see the error:

 NSLog(@"CB-3530 -- original: %@ new: %@", [webView.request.URL description], [request.URL description]);

I added the code just after line 246, where I can get the error printed as follows:
2013-06-24 20:40:01.471 rex[10312:907] CDVWebViewDelegate: Navigation started when state=1

Wow, that is one weird file URL for the new request! This certainly helps, thanks! I'll add this type of URL to the unit tests and re-fix, although I'm certainly curious why the URL is like that - I've never seen that in normal usage :/ Maybe it's a UI framework that is mucking about with things?

I updated the unit tests to test for the malformed fragment, and they all still pass. I think this is a case where this is an error, it still prints the error string, but is harmless since it doesn't report "Load Error" in the location bar.

Assigning to 3.0.0 to get a better fix in to eliminate the error message once and for all. Right now I believe it should never trigger a Load Error in the location bar if it's a navigation to a url fragment

This confirms that is an issue with the hash tag, which is the way JQM navigates. This has been ongoing and I think it would be a good idea to fix this in a 2.9.1 version. I really don't want to wait for 3.0 and a get a whole slew of new issues. Can you please just fix this.

CB-3530 Updated unit tests

What are these "Updated Unit tests" that keep getting posted with a link to a file called CDVWebViewDelegateTests.m? Are these fixes or just tests?

Those are updates. The main commit was earlier: https://issues.apache.org/jira/browse/CB-3530?focusedCommentId=13687461&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13687461

Can we use that to fix the bug?

Of course - why wouldn't you, it is the fix for this bug, it is in the latest codebase.

But the latest version 2.9 still has the same problem, so how could it be fixed?

It's not the same problem - it will never show the error in the location bar anymore. This is still open because of the console log message.
See: https://issues.apache.org/jira/browse/CB-3530?focusedCommentId=13693476&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13693476

Right now this doesn't affect any loading functionality, from what I gather.

Ah, OK. Thank you. I understand now. The bug is only related to the console log and won't effect the app we send to the Apple app store.

Hi everyone, I'm using 2.9 version but I still have this error: Failed to load webpage with error: CDVWebViewDelegate: Navigation started when state=1. So after some time clicking a link, the app crash and the done button of the InApp Browser disappeared, so I'm unable to back to my app. I don't know if this fact could help, but I realized that this error occurs most often in IPad mini.

I appreciate any help, thanks in advance.

Fabian: if you have the crash log, that would be great

Hi Shazron, do you have time to review the crash logs? Thanks in advance

Can't tell anything from that but I think it might be another type of crash unrelated to this one and may be related to the InAppBrowser (even though the error shows, it is benign).

It could be this: CB-4147
