We have signature drawing panel inside of scrollview. To stop scrolling on outer scrollview while drawing , we have put bubbleParent="false" on signature drawing webview.
Until SDK 7.3.1 GA and XCODE 9.2 , signature drawing was working fine. See  [^SDK_7.3.1 GA.mov] 
But with SDK 7.4.0 GA and XCODE 10, the outer scrollview is scrolling. See  [^SDK_7.4.0 GA.mov] 
To Reproduce
Steps to reproduce the behavior, e.g.:
Build app on SDK 7.4.0
Try drawing a signature in white box
See entire page scrolls. Page shouldn't scroll while signing.
Expected behavior
As Sign widget has bubbleParent="false", scrolling should not happen on parent view. 
It works as expected on SDK 7.3.1 GA. But breaks on SDK 7.4.0 GA
Environment
Titanium SDK version: SDK 7.4.0 GA
CLI version: 7.0.6

I tried to run the attached test app in this ticket and it is behaving same in 7.3.0 and 7.4.0 for me. Behaviur is same as attached SDK_7.4.0 GA.mov . [~ewieber]/[~smohammed] Can you please test at your end and let me know the result. Thanks!
There might be an issue between iOS 11.2 (Xcode 9.2) and iOS 11.3+ (Xcode 9.3+). [~Nirmalkumar_Patel] Can you run this test on a iOS 11.3/11.4 device and let us know? I don't think this is a iOS 12 regression, but still a bug.
[~vijaysingh], [~hknoechel] I can reproduce this issue on a device running iOS 11.4 using SDK version 7.3.1.GA and I can also reproduce this issue on a device running iOS 12 on SDK version 7.4.0.GA. This was tested by using the example app mentioned in the description and by using Xcode 10.
Here's a summary of testing on different SDK - Xcode combinations | SDK | CLI | Xcode | Test Device (iOS) | Result | |7.3.1.GA| 7.0.6 | 9.2 | 12, 11.3, 11.4.1 | Pass | |7.4.0.GA| 7.0.6 | 9.2 | 12, 11.3, 11.4.1 | Pass | |7.3.1.GA| 7.0.6 | 9.4 | 12, 11.3, 11.4.1 | Fail | |7.4.0.GA| 7.0.6 | 9.4 | 12, 11.3, 11.4.1 | Fail | |7.4.0.GA| 7.0.6 | 10 | 12, 11.3, 11.4.1 | Fail |
Hi Hans, is this considered a bug to be fixed?
Tested it on iOS 11.1 with Xcode 10. It is working fine. This bug seems to introduced due to some change in WebView in iOS 11.3+ (Xcode 9.3+) from Apple. We faced a WebView related bug TIMOB-25762 in iOS 11.3+ (Xcode 9.3+). I'll look in this.
Simple test case -
var win = Ti.UI.createWindow({ backgroundColor: '#fff' }); var scrollView = Ti.UI.createScrollView({ height: Ti.UI.FILL, width: Ti.UI.FILL }); var outerView = Ti.UI.createView({ layout: 'vertical' }) var redView = Ti.UI.createView({ backgroundColor: 'red', height: 200, width: Ti.UI.FILL }); outerView.add(redView); var greenView1 = Ti.UI.createView({ backgroundColor: 'green', height: 200, width: Ti.UI.FILL }); outerView.add(greenView1); var whiteView = Ti.UI.createView({ backgroundColor: 'white', height: 150, width: 300 }); greenView1.add(whiteView); var webContainerView = Ti.UI.createView({ backgroundColor: 'white', height: '99%', width: '99%', top: '1%', left: '1%', reight: '1%', }); var webView = Ti.UI.createWebView({ left: '0%', disableBounce: true, willHandleTouches: false, url: 'signature.html' }); webContainerView.add(webView); whiteView.add(webContainerView); var yellowView = Ti.UI.createView({ backgroundColor: 'yellow', height: 200, width: Ti.UI.FILL }); outerView.add(yellowView); scrollView.add(outerView); win.add(scrollView); win.open(); var saveCallback = null; var saveSignHdlr = function (evt) { Ti.App.removeEventListener('app:saveSign', saveSignHdlr); saveCallback(evt.inputArray); }; function saveSign(callback){ Ti.API.log('SignWidget', 'saveSign() invoked...'); saveCallback = callback; Ti.App.addEventListener('app:saveSign', saveSignHdlr); Ti.App.fireEvent('app:signatureSave', {message : 'event fired from Titanium, for Signature Save'}); }; function clearSign(){ Ti.API.log('SignWidget', 'clearSign() invoked...'); Ti.App.fireEvent('app:signatureClear', { message : 'event fired from Titanium, for Signature Clear' }); }; function getSign(callback) { Ti.API.log('SignWidget', 'getSign() invoked...'); saveSign(callback); }
