@Paul Stewart verticalScrollPosition is a property not a method so you have to use it similar to a field, like:

Simply add the following code after adding a text to the TextArea:

textArea.verticalScrollPosition = textArea.maxVerticalScrollPosition;

To set the caret at any position in a textArea all u need to do is

textArea.setSelection(beginIndex, endIndex);

if u set the beginIndex & endIndex to the same value (in your case textArea.text.length) the caret will be placed at that positon. If you set it to different values, text in that range will be highlighted.
