Failed to execute 'initMouseEvent' on 'MouseEvent': parameter 15 is not of type 'Even

[Manoj Solanki]

I created a skeleton app using Sencha CMD 6.2.1 & Sencha touch 2.4.2, the app loads properly on browser but throws Uncaught TypeError: Failed to execute 'initMouseEvent' on 'MouseEvent': parameter 15 is not of type 'EventTarget. at Class.onEvent (TouchGesture.js?_dc=1482839675019:117)' in console when I tap & scroll the view up & down.

I am using following:
Sencha touch version: 2.4.2
Sencha CMD version: 6.2.1
OS version: Windows 7
Browser version: Chrome 55.0.2883.87

here I have attached screenshot of the same.

I built a sample application but I was unable to recreate this error. Do you see it every time?

@Gary Schlosberg, I am also facing same issue in my project. So I created a skeleton app and tried it as @Manoj Solanki reported, this issue occur if I scroll the view up & down many times and click on the view in between. I have created a video of how it is occurring, please check it

I've still been unable to recreate this. So you're not using the emulator in your test? Are you creating the application from the Touch SDK directory or from the directory in which you are creating the application? What command are you using to create the application?

1) No I am not using emulator, I tried it on my pc here are details:
Browser: Chrome browser(55.0.2883.87)
OS: Windows 7 desktop
Sencha touch framework version: 2.4.2
Sencha SDK version: 6.2.1.29

2) I created skeleton app by executing command: sencha -sdk 'E:\touch-2.4.2' generate app MyApp 'E:\MyApp'

3) I generated app by executing above command from Sencha CMD folder(i.e. C:\Users\Gaurav.Darak\bin\Sencha\Cmd\6.2.1.29) & also from my app's folder, but in both cases I got the error.

@Gary Schlosberg, are you able to recreate the error? I have mentioned my steps in previous message, am I doing something wrong?

In Sencha, They have used made mistake in parameter passing in initMouseEvent()
