TextField data is displayed in multilines if mapped from the data of a textarea. And one of the middle lines are only displayed on the text field. you cannot see the entire data unless you start deleting.
Actually data should have been displayed in single line with return characters as separators between the data of different lines.
Steps to reproduce
------------------
1.Copy the sourcecode to MyPanel.java and compile.
2.Put focus onto TextArea and start typing in some thing. Make sure you have multi lines of data typed in.
3.Press First Button 'TextAreaToTextField' and see that the data in text area is mapped into the text Field.
4. notice that only part of the data is visible and mostly one of the middle lines displayed.
Try traversing through. you cannot traverse through any of the lines other than the visible one.
Try using backspace to delete .
see that the initial lines of data appears.

ALSO:

TextField is converted to TextArea when data from a text area is mapped in to text field and then text area data is deleted.

Steps to reproduce.
------------------
1.Copy the soucecode to a file MyPanel.java and compile.
2.Run the program.
3.Enter in multi lines of data into text area.
4.Press first button TextAreaTotextField.
5.text of text area gets mapped to textfield.
6.delete data in text area completely, now text field converts itself to text area.
