[TIMOB-20372] Windows: Ti.App.fireEvent and listener doesnt work in static javascript/html page loaded in webview

While building a simple app for all three platforms we used leaflet map with webview. While android and ios had no issues communicating with javascript embedded in web page, there is no communication with webview on windows phone platform. I have made a simple project in which i can get response in android/ios but not windows phone: logging.html fromWebView index.js var win = Ti.UI.createWindow(); var webview = Ti.UI.createWebView({ url: 'logging.html' }); var button = Ti.UI.createButton({ title: 'fromTitanium', height: '50dp', width: '130dp' }); button.addEventListener('click', function(e) { Ti.App.fireEvent('app:fromTitanium', { message: 'event fired from Titanium, handled in WebView' }); }); Ti.App.addEventListener('app:fromWebView', function(e) { alert(e.message); }); win.add(webview); win.add(button); win.open();
