		"description": "h4. Problem Description\r\nWhen trying to remove view in \"scrollend\" event, I'm getting crash. \r\n\r\nh4. Steps to reproduce\r\n1. Create a new mobile project (Classic Titanium)\r\n2. Replace the contents of app.js with this code: \r\n{code}\r\nvar win = Ti.UI.createWindow();\r\n\r\nvar colors = [ '#f23', '#246', '#48b', '#842', '#b47' ];\r\nvar currentIndex = 0;\r\n\r\nfunction createView() {\r\n\tvar view = Ti.UI.createView({ backgroundColor: colors[currentIndex] });\r\n\tcurrentIndex = (currentIndex + 1) % colors.length;\r\n\treturn view;\r\n}\r\n\r\nvar scrollableView = Ti.UI.createScrollableView({\r\n\tviews: [ createView() ],\r\n\tscrollingEnabled: false,\r\n\tshowPagingControl: false\r\n});\r\n\r\nscrollableView.addEventListener('scrollend', function() {\r\n\t// scrollableView.removeView(0); // doesn't work\r\n\tTi.API.info('scrollableView.views ');\r\n\tTi.API.info(scrollableView.views.length);\r\n\tscrollableView.removeView(scrollableView.views[0]); // crash\r\n\t// scrollableView.setViews(scrollableView.views.unshift()); // crash\r\n});\r\n\r\nscrollableView.addEventListener('singletap', function() {\r\n\tscrollableView.addView(createView());\r\n\tscrollableView.moveNext();\r\n});\r\n\r\nwin.add(scrollableView);\r\nwin.open();\r\n{code}\r\n3. Run in a device\r\n4. Scroll to the end, while checking the logs. \r\n\r\n\r\nh4. Extra information\r\nFirst issue is that passing view index to \"removeView\" method doesn't do anything, although it's documented it works.\r\n\r\n{code}\r\nTiScrollableView: (main) [32757,41129] removeView() ignored. Expected a Titanium view object, got Integer\r\n{code}\r\n\r\nSecond issue is crash. Just tap on screen to see the issue. Here are logs:\r\n\r\n{code}\r\n11-11 11:15:50.749: E/AndroidRuntime(14644): FATAL EXCEPTION: main\r\n11-11 11:15:50.749: E/AndroidRuntime(14644): Process: com.tipsyandtumbler.testing, PID: 14644\r\n11-11 11:15:50.749: E/AndroidRuntime(14644): java.lang.IllegalStateException: The application's PagerAdapter changed the adapter's contents without calling PagerAdapter#notifyDataSetChanged!
