The compiler has another opinion. (incompatible types found)

That's a good idea.

Thank You. That solved my problem. I'm really glad.

Here is my new source code:
void makeParagraph(HTML.Tag paragraphType)
{
   if( textEditor instanceof JEditorPane )
   {
     HTMLDocument  htmlDoc = (HTMLDocument) textEditor.getDocument();
     int           position = textEditor.getSelectionStart();
     Element       elem = htmlDoc.getParagraphElement(position);

     if( elem instanceof HTMLDocument.BlockElement )
     {
       HTMLDocument.BlockElement block = (HTMLDocument.BlockElement)elem;

       SimpleAttributeSet  newType = new SimpleAttributeSet(
         block.getAttributes()
       );
       newType.addAttribute( AttributeSet.NameAttribute, paragraphType );
       htmlDoc.setParagraphAttributes(position, 0, newType, false );
     }
   }
}

This function does now exactly what I want. 8-))))

Thank You again for your help.
