Alex Harui commented on FLEX-34033:
-----------------------------------
Most of the time, the SDK does not check for bad programmer input. I would
rather not scan every string being assigned to a text widget for newlines. If
you assign really long strings that could affect performance. I think you'll
have to scan it before assigning if you suspect that it might contain newlines.
> single-line TextInput keeps a newline when TextInput.text = "abc\n".
