Description

I'm trying to delete an event created within a webview, via an app event. This produces an error : [ERROR] Error firing event 'app:deleteWebviewEvents': A JavaScript exception occurred - The problem *is present* with the Titanium SDK *8.0.0.v20190219113758*. - The problem *is not present* with the Titanium SDK *7.5.1GA*. the error does not allow the removal of the event "clickFromApp", in fact, by pressing the "app --> webview" button again, the event is called again. *Steps to reproduce:* - Create a Classic "Default Project" app - Replace the "app.js" code with the attached "app.js", and insert into the project also the file webview.html attached. - Build with Titanium *8.0.0.v20190219113758* and run on iOS. - Test the logic: press "app --> webview" button, press "webview -> app" button, clear the event of the webview with the button "clear events". - This produces the error "[ERROR] Error firing event 'app:deleteWebviewEvents': A JavaScript exception occurred " - Retry with SDK 7.5.1GA, in this case there are no problems. The event is deleted, and the button "app --> webview" it doesn't call anything anymore.

Hello [~nicolomonili], I was able to reproduce the issue with SDK 8.0.0.v20190219113758 in iOS. The same code works without error in SDK 7.5.1.GA. Moving to TIMOB. Thanks.
