JTextPane.modelToView() exception

Show all headers | View raw

I am getting a BadLocationException from a call to textpane.modelToView() 
when the position I pass should be legal.

I create a JTextPane and get its document:
   JTextPane jtp = new JTextPane();
   Document doc = jtp.getDocument();
Then I add a document listener to the document.

This is inside a DocumentListener's insertUpdate() method:
public void insertUpdate( DocumentEvent event ) {
   Document doc = event.getDocument();
   int len = doc.getLength();
   if ( len > 0 ) {
      try {
         Rectangle view = jtp.modelToView(len-1);
         // do other things here
      } catch (Exception e) {
         e.printStackTrace();
      }
   }
}

Everything is fine until I enter the first character after a newline.
Then I get a BadLocationException: Position not represented by view
(I am using Java 1.6, on a Windows 7 platform)
