If you make a TextField (or TextArea) read-only by calling setEditable(false), there is no blinking cursor when the text field has focus.

This is an issue for keyboard only users, as you can use the cursor keys to move within the text field and select text, but this is difficult to do if the current cursor position is hidden.

As an example of correct behavior, right click on a file or folder in Windows Explorer and bring up properties. Click in the Location field. A blinking cursor appears where you clicked, and you can use the keyboard to move and select parts of the location text easily.
