Cannot change Bold to Normal in HTMLEditorKit

Question

We have a JTextPane based HTML editor which use HTMLEditorKit. Once we mark some text as bold the HTML formed contains the <b>....</b> tag correctly. But opening the document next time, even if we remove the bold attribute from characters and even if they appear as Normal on screen of JTextPane... the HTML formed still contains the <b>...</b> tags. Those are not removed. So text once turned bold cannot be turned back to Normal.
Please help.

We use JDK 1.3.1.
Actually what we do is..
Action aBold = new StyledEditorKit.BoldAction();//define action
aBold.putValue(Action.NAME, "Bold");//is this needed??
tbtnBold = new JToggleButton((Action)aBold); //associate action with a toggle button
//add a listener to the button.. a listener again !! why? I'm not sure. This listener toggles the bBoldFlag as required.
tbtnBold.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e)
if(bBoldFlag)
bBoldFlag = false;
else
bBoldFlag = true;
// from other part of code where attributes of selected text needs to be changed as a "format font" dialog box... the bBoldFlag is checked to decide whether text should be bold or normal. like....
if(bBoldFlag)
StyleConstants.setBold(aSimpleAttributeSet,true);
else
StyleConstants.setBold(aSimpleAttributeSet,false);
This code was developed by previous developer. So its getting tough for me to justify each part of code. Thanks for your help... in advance.
