I'm running the latest version of EO.WebBrowser (2016.0.24) and I am experiencing a regular problem with closing WebViews.
I am getting the EO Exception report, pasted below. I originally suspected a problem in some code we execute before close, but it doesn't seem to be the issue after some investigation, I think this may be a bug in EO?
The issue started once I upgraded to the first 2016 release.
On my end I reproduce the issue by opening a web view, closing it, then opening a new web view and closing that.
We register JS callback handlers and before we close the window we are calling EvalScript to run some code before we close the view.

I've removed this to make the post easier to follow, I'll keep it on hand incase it is needed again.
This post was for the crash report.

One other thing I just noticed. We have a web-view that remains open at all times, and once the first crash happens I can't reproduce the crash with a single web-view open.
If I open two new web-views, and close one then both crash when it exists, creating a Channel disconnected exception like before.

Is there any way to look at the information contained in the crash post, maybe it can give me some insight into the problem so I can further my investigation?

Hi, We will post a new build today that will contain a number of fixes. I recommend you to wait for that build first, then set EO.Base.Runtime.ApplicationID in your application. This would allow us to associate the crash report in our database to your application. See here for more details: http://www.essentialobjects.com/doc/common/crash_report.aspxOnce you experience the crash again let us know and we will look into the report to see what we can find. Thanks!

Thank you for the information, unfortunately I actually have to disable the automatic crash reporting so I wont be able to associate an ID.
I'll update once the build is posted and I've tested.

I've updated to 2016.0.28.0 and I'm still experiencing the crash issue. Should I send in a crash report?

Yes. Please. You can set the ApplicationID and then PM us your ApplicationID. We will then look into our crash database to see what we can find.

Hi There,
I am having the same problem, I am on this version 16.0.49.0 and the view crached on close.
I open multiple web views with different URL and If I closed any of them whole things crashed. and says webview disposed or so!
Any help?

Hazem,
I found that I was closing my WebView's by Disposing the WebView and WebControl directly. Switching to calling Close solved the problem for me.
EO informed me that these methods should function the same, however this was the only change I made to resolve the problem and have since no longer experienced the problem.

Hi, Thanks for sharing by James. If either of you can create a test project and send the test project to us, it will be very helpful for us to get to the bottom of this issue. Please see here for more information on how to send a test project: http://www.essentialobjects.com/forum/test_project.aspxThanks!

I will take another stab at creating a test project for this when I have some extra time. However I was previously unable to reproduce the problem in isolation. My application is fairly complex with a lot of interaction with the browser, so it will be difficult to isolate the issue.

Thanks James a lot, I was doing the same and calling the close instead of dispose does solve the problem.
I also created a project and sent it to you.
