In iOS, we've been using this piece of code to insert a view into a ScrollableView before the last element:
/* initialize default window */
var win = Ti.UI.createWindow({backgroundColor: 'white'});

/* initialize ScrollableView */
var sv = Ti.UI.createScrollableView({
	views: [Ti.UI.createView({backgroundColor: 'red'})]

/* actual test */
var views = sv.views;
try {
	views.splice(views.length - 1, 0, Ti.UI.createView({backgroundColor: 'green'}));
} catch (e) {
	Ti.API.error(String.format("Exeption: %s", e));
sv.views = views;
Now, on Android the splice() call in the code yields this exception: "Cannot find default value for object." This forces us to create a temporary array, populate it and then set the new array as the view array of the ScrollableView:
var views = [];
for(var i = 0; i < sv.views.length; i++) {
views.splice(views.length - 1, 0, Ti.UI.createView({backgroundColor: 'green'}));
sv.views = views;
This code is more verbose than necessary, it may introduce bugs (e.g. typos) and it is inconsistent with the behavior on iOS. Please fix.

    Thanks for raising this ticket. In order for me to escalate it to the core team, all the fields must be complete. Please check it against the [JIRA Ticket Checklist](https://wiki.appcelerator.org/display/guides/How+to+Submit+a+Bug+Report#HowtoSubmitaBugReport-JIRATicketChecklist), and add any missing information. Furthermore, a test case must run without modification, as per the [Creating a Test Case](https://wiki.appcelerator.org/display/guides/How+to+Submit+a+Bug+Report#HowtoSubmitaBugReport-CreatingaTestCase) section. I will mark this resolved for now. Please reopen it once it is complete, and I will move it to the main project. Cheers

    Updated the code example to be standalone.

    Sven I have tested this, and it has been fixed in Be aware for future that the environment field should only contain the versions of each component that exhibits the issue. Hence, only include the versions that you have physically tested. Cheers
