Description

To produce the error - quickly delete line item one after another and eventually crash will happen

var win = Ti.UI.currentWindow;

var listView = Ti.UI.createListView();



var sections = [];
var fruitSection = Ti.UI.createListSection({
	headerTitle : 'Fruits'
});
var fruitDataSet = [{
	properties : {f
		title : 'Apple',
		canEdit : true
	}
}, {
	properties : {
		title : 'Banana',
		canEdit : true
	}
}, {
	properties : {
		title : 'Pineapple',
		canEdit : true
	}
}, {
	properties : {
		title : 'Kiwi Fruit',
		canEdit : true
	}
}, {
	properties : {
		title : 'Coconut',
		canEdit : true
	}
}, {
	properties : {
		title : 'Strawberry',
		canEdit : true
	}
}, {
	properties : {
		title : 'Watermelon',
		canEdit : true
	}
},{
	properties : {
		title : 'Mangosteen',
		canEdit : true
	}
},{
	properties : {
		title : 'Lychee',

	properties : {
		title : 'Orange',
		canEdit : true
	}
},{
	properties : {
		title : 'Guava',
		canEdit : true
	}
}];
fruitSection.setItems(fruitDataSet);
sections.push(fruitSection);


listView.sections = sections;
win.add(listView);

This is a serious problem prevents me from submitting my app!!! Please treat it urgently and get it fixed ASAP. Thanks
Shuo Liang 2014-07-07

Hi, Can you tell me which kind of device do you use, as I tried your code with different simulators. But can't reproduce your problem. Does this error happen when you run your simple test case or you have other code in your test case. On the other hand, would you please try to clean project, then run your app again. See if the problem still is there. Regards, Shuo

Hi Shuo Tried on iOS simulator 7.1. Try as quickly as possible to delete the line item - I can recreate this issue consistently, Code snippet is fairly enough for issue reproduction. Will try to clean the project and get back to you later Thanks

Hello, We tested this issue. We cannot reproduce this bug in latest Ti Tools.

Testing Environment:

Titanium SDK: 3.3.0.GA, Titanium CLI: 3.3.0, IOS Simulator: 7.1, OS X Version: 10.9.3, Appcelerator Studio: 3.3.0

Steps to Test:

1. Create a Classic project. 2. Paste this code in app.js file. 3. Run this code with the testing environment.

   function getInsertDataIOS(insertCount, sectionIndex, itemIndex, message, animation) {
   	var data = [{
   		properties : {
   			itemId : message
   		},
   		template : 'myCell',
   		mainLabel : {
   			text : insertCount + ' Insert at ' + itemIndex + ' in Section ' + sectionIndex + ' Animation ' + animation
   		},
   		childLabel : {
   			text : 'Insert ' + message
   		}
   	}];
   	return data;
   }
   
   function getInsertDataAndroid(insertCount, sectionIndex, itemIndex, message) {
   	var data = [{
   		properties : {
   			itemId : message
   		},
   		template : 'myCell',
   		mainLabel : {
   			text : insertCount + ' Insert at ' + itemIndex + ' in Section ' + sectionIndex
   		},
   		childLabel : {
   			text : 'Insert ' + message
   		}
   	}];
   	return data;
   }
   
   function getData() {
   	var data = [{
   		properties : {
   			title : 'bad index=100. check parity',
   			itemId : '101',
   			height : 44
   		}
   	}, {

Probably it has been fixed in latest SDK 3.3.0 Please close it. Thanks

I am seeing this issue now consistently with all my editable ListViews, after upgrading my iPhone to iOS 8 today. It happens when I swipe to reveal the Delete button, then tap somewhere on the list, or swipe back to hide it. Xcode device console logs hundreds of these warnings when it happens and then crashes the app: {quote} : reloading table view while we're in swipe to delete mode but we don't have a proper swipe to delete index path {quote} I'm running iOS 8 (device), with Ti SDK 3.3.0. I had seen this issue occasionally with iOS 7.1.2, but it was rather rare and you had to swipe really fast. With iOS 8, it happens all the time. I have not upgraded to Xcode 6 and iOS Simulator 8 yet, so I don't know if it can be reproduce there yet. Is anyone else experiencing this as well?
David He 2014-09-18

Ed How did you test it? Use my code above? Please refer to Shuo to reopen this ticket. Thanks
Mauro Parra-Miranda 2014-09-24

Tested with latest 3.4.0.RC, working fine.
