Could you please check.
Thank you in advance.

for (let i =0; i <100; i++) {
tableData.push({ title: i = ${i} });

Below comment was made pre-coffee, I was testing against 9.2.2.GA... I can confirm this issue is a regression in 9.3.0.GA -[~andreas.pingas] I'm unable to reproduce your issue based on the following code, the
scrolllistener is firing when I scroll the TableView. Could you please provide a minimal sample to reproduce this issue-master: https://github.com/appcelerator/titanium_mobile/pull/12348
FR Passed, waiting on Jenkins build.
merged to master, backport for 9_3_X merged for 9.3.1 target.
Note that with the fix above I get the following crash when scrolling a listview with zero items in the first section: java.lang.ClassCastException: ti.modules.titanium.ui.widget.listview.ListViewProxy cannot be cast to ti.modules.titanium.ui.widget.listview.ListSectionProxy at ti.modules.titanium.ui.widget.listview.TiListView.generateScrollPayload(TiListView.java:263)
Able to reproduce the issue mentioned above using the following test case
const window = Ti.UI.createWindow(); const emptySection = Ti.UI.createListSection({ headerTitle: "I'm an empty Section" }); const listItems = []; for (let index = 0; index < 100; index++) { listItems[index] = { properties: { title: "Row " + (index + 1).toString() } }; } const listSection = Ti.UI.createListSection({ headerTitle: "List Section" }); listSection.items = listItems; const listView = Ti.UI.createListView({ canScroll: true, }); listView.sections = [emptySection, listSection]; window.add(listView); window.open();
