Subject [jira] [Commented] (PIVOT-772) Exceptions thrown when calling getCharacterBounds of TextArea when incomplete lines exist
Date Thu, 05 Jul 2012 07:38:34 GMT

    [ https://issues.apache.org/jira/browse/PIVOT-772?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13406892#comment-13406892
] 

Magic Xie commented on PIVOT-772:
---------------------------------

EventQueue.invokeLater(new Runnable() {
	@Override
	public void run() {
	   Bounds b = textArea.getCharacterBounds(textArea.getCharacterCount());
	   textArea.scrollAreaToVisible(b);
      }
});

is that helps?
