Hello,

I'm looking at upgrading from EO 2017 to EO 2020, and I noticed the WebView's JSExtInvoke is no longer working; our event handlers are never being called when our Angular JavaScript code attempts to make a callback into our C# code.

Is this a known breaking change?
Any ideas or suggestions how to get the JSExtInvoke event working again?

Thanks & Regards,
Greg

Thank you for the tip about the built-in debugger feature; that was very helpful!

We are using C# Windows Forms, and our Angular code was doing this:

declare var EOWebBrowser: any;
EOWebBrowser.ExtInvoke(...

When I used the built-in debugger, I was able to see in the console that we are getting the error:

Error: Exception Thrown by ...:: eoWebBrowser is not defined

I couldn't find EOWebBrowser related to extInvoke in the EO documentation, so I'm unsure where we obtained that from?

I changed our code to the following to match what I see in the EO documentation which fixed the problem for us.

declare var eoapi: any;
eoapi.extInvoke(...

Thanks!
Greg
