DefaultStyledDocument.styleChanged() question

[borbjo]

I use this method to notify the document that a style has changed. It works fine for Paragraph Styles - but not for Character Styles.

Character Styles = styles added with doc.setCharacterAttributes(offset, length, s, replace);

Paragraph Styles = styles added with doc.setParagraphAttributes(offset, length, s, replace);

Anyone know why styleChanged() will change the look of the text for paragraph styles but not for character styles?
