Font color issue with inserted HTML content in JTextPane (HTMLEditor)

Question

Hi everyone,
I have a very serious issue with the HTMLEditor I'm developping. This editor is a little bit special since it is intended to edit blocks of HTML content that are loaded when the editor is initialized.
You can in fact decide to keep this loaded HTML content or start a new HTML document from scratch. Alright, now my issue is the following :
When text is loaded, it's properly rendered. I have a functionality which let's you see the HTML code from the HTML document used in the editor, so I can check and see if code is correct, and yes, it's correct.
The problem is that when I try to change the color attribute of some text on my loaded content, nothing happens ! I don't know what's the matter with this bug, I only have it with the color attribute, with every other attribute everything's fine (font, size, etc.)
The funny thing is that, after I change another attribute for loaded content, like font family, then changing color attribute funcionnality starts to work again !
I've also noticed that I don't have any of these problems when I start my HTMLDocument from scratch (when I create a new HTML document and start typing text).
Another weird thing, is that I have a feed-back feature in my editor which reflects attributes for text over which the caret is positionned. For example, if you put caret over red text, the color combo box displays a red value, you know, just like in MS Word. Well, with my loaded content if I have a red text color and I decide to put it in green, the color combo box displays the green value when I click over text for which I have changed color, but in my JTextPane it's still red !! And when I try to see the HTML code generated nothing has changed, everything is still red !
There is something really strange here, this means that when I get the attributes of the loaded text from the HTMLDocument, color appears to be green, but when it gets rendered in the JTextPane it's still red and when it gets anlyzed to produce the corresponding HTML code, these changed attributes are not taken into account.
But the most weird thing above all, is that I don't have this bug everytime, sometimes I start my HTML editor applet and it works fine, and some other times this color issue is bakc there. Is this a known bug for Swing API or not ?
=============
This is more or less my technique :
//I declare a global reference to my HTMLDocument
HTMLDocument _docHTMLDoc;
//Create a JTextPane
JTextPane _tpaEditor = new JTextPane( );
//Set type content to automatically select HTMLEditorKit
_tpaEditor.setContentType("text/html");
//Get a referene to its HTMLEditorKit
HTMLEditorKit _kitHTMLEditor = (HTMLEditorKit) _tpaEditor.getEditorKit( );
//I then have a function to create new documents
void newDocument(){
  _docHTMLDoc = (HTMLDocument) _kitHTMLEditor.createDefaultDocument();
  _tpaEditor.setDocument(_docHTMLDoc);
   //I do other stuff wich are not important to be shown here
//I then have another function to load content
void loadContent(){
   //I get content from a HashMap I initialized when I started my applet
   String strContent = (String)_mapInitParameters.get("html_content");
   //I set content for my editor
   _tpaEditor.setText(strContent);
//Notice.. I have tried many other ways to load this text : via HTMLEditorKit and its insertHTML method, I
//have also tried to store this content in some reader and make HTMLEditorKit read it... and nothing,
// I always get the bug
//To change color it goes like this :
JComboBox _cboColor = new JComboBox();
//I correctly initialize this combo with colors
//then I do something like this
ActionListener _lst = new ActionListener(){
   public void actionPeformed(ActionEvent e){
      Color colSel = (Color) _cboColor.getSelectedItem();
      MutableAttributeSet mas = new SimpleAttributeSet();
      StyleConstants.setForeground(mas,colSel);
      setAttributeSet(mas);
_cboColor.addActionListener(_lst);
//Set Attributes goes something like this
private void setAttributeSet(javax.swing.text.AttributeSet atrAttributeSet) {       
        //Get current 'End' and 'Start' positions
        int intCurrPosStart = _tpaEditor.getSelectionStart();
        int intCurrPosEnd = _tpaEditor.getSelectionEnd();
        if(intCurrPosStart != intCurrPosEnd){
            //Apply attributes to selection
            _docHTMLDoc.setCharacterAttributes(intCurrPosStart,intCurrPosEnd - intCurrPosStart,atrAttributeSet,false);
        else{
            //No selection : apply attributes to further typed text
            MutableAttributeSet atrInputAttributes = _kitHTMLEditor.getInputAttributes();
            atrInputAttributes.addAttributes(atrAttributeSet);

hi, friend!
try this:
void setAttributeToText(JTextPane pane, int start, int end, Color color) {
MutableAttributeSet new_att = new SimpleAttributeSet();
StyleConstants.setForeground(new_att,color);
HTMLDocument doc=(HTMLDocument)pane.getDocument();
doc.setCharacterAttributes(start,end,new_att,false);
It works fine in my Application, hope will work in yours, too.
good luck.
