Hi Eric,
Here is a sample code. When user enters [ENTER] key, you will see the behavior is correct although you will get a pair of <p></p> tags. This is the way I do it. The problem is that when you want to display saved html in JTextPane next time, you have to replace all <br> tags to <p></p> tags. I am not sure if this will help you or not. As I said before this is the way I solved the problem before deadline and you may overwrite [ENTER] key or add [SHIFT][ENTER] to yourTextPane's keymap. Good luck to you.
