    Hello, This is a valid bug in Scrollview with Label. The label doesn't show inside a scrollview when the label character exceeds 13k. I have tested the reported sample code in SDK 5.1.1.GA with iOS 9.1. I have observed the same result. The label vanishes when the character length exceeds 13k. I tried to test the behavior without the scrollview and the I saw that it works. The label doesn't vanishes. So it's a bug in scrollview to limit the label character. 
       Titanium.UI.setBackgroundColor('#FFF');
   var window = Ti.UI.createWindow();
   var Name = Ti.UI.createLabel();
   var CallBtn = Ti.UI.createButton({
       title : "Test",
       bottom : 50,
   });
   CallBtn.addEventListener('click', function(e) {
       var labelLength = 1000;
       setInterval(function() {
           console.log(labelLength);
           Name.text = Array(labelLength).join("a");
           labelLength += 1000;
       }, 1000);
   });
   window.add(Name);
   window.add(CallBtn);
   window.open();

    My Environment

    OS X El Capitan 10.11.2 XCode 7.1 iPhone Simulator 6s Plus / iOS 9.1 Ti SDK 5.1.1.GA Thanks.

    This happens only on iOS

    Any known workarounds?
  4. David Benko 2015-12-28

    Possible workaround: Split the text in multiple labels. Having multiple labels with less than 13k characters inside the scrollview does not cause the bug One note: it appears that the bug is not about character limit, but size of the label. If you have a lower font size, its possible to have more than 13k characters without the label vanishing
