How to insert HTML content directly in code from JEditorPane ?

Question

I'm developping an HTML Editor on a JEditor Pane.
The problem is that a blank is not interpreted, and i've tried to add "& n b s p ;" in the code from a KeyListener added to the VK_SPACE event, or to define an Action to add HTML Spaces. But i didn't achieve to...
I just want to insert a "& n b s p ;" in the HTML code of the document displayed in the JEditor evry time the SpaceBar is pressed.
I've tried InsertContentAction() :
Not a solution :It inserts " & n b s p ;" in the text (it appears litteraly).
I've tried InsertHTML. But it needs a tag parameter, and in my case, i need no tag
to be inserted.
I'm stuck since days... Any help woul be extremely appreciated...

The code I now have is:
TextAction actInsertNBSP = new TextAction("insert-space"){    
public void actionPerformed(ActionEvent evt){
//Where is the cursor now
int intInitialCaretPos = text.getCaretPosition();
try{       
     //Make HTML document to add the html code
     HTMLDocument htmldoc = (HTMLDocument)text.getStyledDocument();
     //Get document input attributes before insert
     AttributeSet atr = kit.getInputAttributes().copyAttributes();
     //Insert tag
     kit.insertHTML(htmldoc,intInitialCaretPos,"<b>\240</b>", 0, 0, HTML.Tag.B);
     //Set stored attributes to input attributes
     kit.getInputAttributes().addAttributes(atr);
     //Set cursor on right position
     text.setCaretPosition(text.getCaretPosition());                    
     }catch (Exception exc){
          exc.printStackTrace();
KeyStroke kstSpace = KeyStroke.getKeyStroke(KeyEvent.VK_SPACE, 0);
text.getKeymap().addActionForKeyStroke(kstSpace,actInsertNBSP);
