Chrome Extension Sendmessage From Popup.html To Content.js Not Working

I'm trying to build an Extension which sends data from the popup.html to the tab dome, but I can't get the sendMessage to work and I don't understand why. I'm following this guidli

Solution 1:

oops, I think you just send message to popup.js itself...

getSelected in popup.js listen the activity of popup tab(it is a tab in chrome too) thus, the tab id is actually the popup tab, not the tab where your content.js are inserted

BTW getSelected is deprecated. Try alternatives? http://developer.chrome.com/extensions/tabs.html#method-getCurrent

Solution 2:

Ok, I'm stupid... the wrong thing was... the inspector page I was watching. "console.log" inside of the content.js prints on the TAB INSPECTOR CONSOLE not on the extension one!

I hope it will help others.
