OnWebKitInitialized and OnProcessMessageReceived not invoked

[sepviz]

Hi,
I'm trying to modify the cefsimple example on mac with CEF3. I send a message in the OnLoadEnd method of the browser process, and it returns true, but it seems that the OnWebKitInitialized and OnProcessMessageReceived methods of the renderer process are never invoked.

I modified process_helper_mac.cpp to invoke CefExecuteProcess(main_args, <MY_APP>, NULL) and I can see with logging that the constructor of <MY_APP> is correctly invoked, as well as the GetRenderProcessHandler and OnRenderThreadCreated methods. However, no other method of this object is invoked (it implements CefApp, CefRenderProcessHandler and CefBrowserProcessHandler, and I put logging in all methods). I am obviously missing something but I don't know where to look at.

What are the required steps to have OnProcessMessageReceived invoked when sending a message to the renderer process?

What CEF3 version are you using? How are you logging? It's hard to say what you're doing wrong without looking at your code. Can you post it?

I use the prebuilt package for mac 64 bits CEF 3.1916.1857 found on cefbuilds.com. For logging, I open a file in append mode, write to it and close it everytime I want to log something.

What I'm trying to do is to port to mac an app that already works fine on Linux and Windows. Since the architecture is a bit different for mac, the code for Linux/Windows has been successfully modified to use a separate process helper, so that we don't have to make any modification to our code when porting it to mac.

i have attached a zip file containing the main classes. I have removed most of the non-CEF related code from it. To run this on mac, I use PayloadEditor from the main entry point and JavaScriptApp in the secondary entry point. Let me know if you need more details.

This may not work due to sub-process sandbox restrictions. Try adding the `--no-sandbox` command-line flag.

It worked indeed with this option. Since it was possible to log from some methods of this class, I had incorrectly assumed that there was no sandboxing issue.

Thanks!
