Hi Michael,
Thanks for the response. It was my fault after all! Setting the signal /
webkit_user_content_manager_register_script_message_handler calls on the
wrong content manager instance.
Things work as expected now from JS in the web content (I do want the
web content to be able to post messages to the C counterpart).
Apologies for the noise,
Antonio

The fact is that I'm trying to receive messages from a <script> in my

call, as indicated in [1], but "window.webkit" is undefined.
I think it's only going to be defined for JS executed via WebKit API,
not for JS that's defined by your web content? Otherwise random web
content would be able to talk to your internal message handlers, and
that's probably not good.
Try webkit_web_view_run_javascript() in the UI process, or
jsc_value_object_invoke_method() in the web process.
