WPF application crashes when closing a PDF containing XFA form #4701
Comments
As the problem is within CEF, not directly in |
Upstream issue chromiumembedded/cef#3644 I'd suggest you add any additional relevant information there. |
In reference to your answer #4701 (comment) The issue of crashing cef when opening the PDF form is fixed now. But my problem still persists: the CefSharp.Wpf.Example application crashes when it's closed or when the tab containing the PDF form is closed. It's still the same like in the issue description above. This problem does not occur when opening and closing the PDF form in the CefSharp.MinimalExample.Wpf application. The application closes normally without any As this only seems to occur in a WPF tabbed application I am not sure how to report it in cef issue tracker. Can you give me any advice? Do you need some additional information? Output CefSharp.Wpf.Example (starting directly before the PDF form is opened). (debug.log)
Output CefSharp.MinimalExample.Wpf (starting directly before the PDF form is opened). (debug.log)

After upgrading to recent version 121.3.130 the problem disappeared :-) |
Is there an existing issue for this?
CefSharp Version
120.2.70
Operating System
Windows 11
Architecture
x64
.Net Version
.Net 4.8
Implementation
WPF
Reproduction Steps
The application CefSharp.Wpf.Example crashes when closing a tab which contains some kind of XFA form. Until now this only occurs when the XFA form triggers a JsDialogHandler (at least I had no issues with forms without a JS-Dialog). Maybe it's also related to PDF version 1.7 (with version 1.6 I had no issues).
I have exactly the same problem in my own application when closing a tab.
Steps to reproduce:
Das Programm "[36100] CefSharp.Wpf.Example.exe" wurde mit Code 3221225477 (0xc0000005) 'Access violation' beendet.
Expected behavior
The tab can be closed without any issues.
Actual behavior
Application crashes.
