    No offsetParent in Firefox?

    In XHTML mode (application/xhtml+xml) Firefox does not know offset
    properties (offsetParent/Left/Top). In all the other browsers it works.
    Does someone has the same problem or knows a solution for this?
    Example:

    ....
    <body>

    <div><div id="hello">Hey </div></div>

    <div id="debug"></div>

    <script type="text/javascript">
    //<![CDATA[
    alert(document. getElementById( 'hello').offset Parent);
    //]]>
    </script>

    </body>
    ....

    In Firefox offsetLeft and offsetTop is 0, the script above shows null
    as result. Can somebody help me?

      XHTML MIME types are not ready for prime time in a lot of respects :-P
      For example, there is no such thing as incremental loading of an XHTML
      document served with the proper MIME type.

      If you're keen on using application/xhtml+xml anyway, you might ask in
      mozilla.dev.tec h.javascript on news.mozilla.or g - they will be far
      better equipped to handle mozilla-specific javascript questions.

      Also try mozilla.dev.tec h.dom.

          Thank you, I have posted on mozilla.dev.tec h.dom. Although - is there
          an other way to find out the real position of an element to a parent
          one?

              I am sure it is available if you wait for the page to be loaded. Mozilla
              so far for XML parsing and rendering has no incremental approach that
              would allow script called _during page load_ to get such values correctly.

                      I haven't tried it out but i am sure itr works. In the mozilla dev
                      group they said that the Gecko engine does not builds up the dom (or
                      whatevery) completely until the complete page ha been loaded. After
                      complete loading offsetParent etc are computed, so I have to take
                      onload or domload..
