Hi there,

I've come across a very strange behaviour related to iframes with media content displayed on IE9; just try:

<window id="main" title="My First Window" border="normal" width="640px" height="480px">
    <zscript>org.zkoss.util.media.Media media = null;</zscript>
    <button id="bupload" label="Upload" upload="true" onUpload='media = event.getMedia();' />
    <button id="show" label="Show uploaded file in iframe within a modal window">
        <attribute name="onClick"><![CDATA[
        Window mw = new Window();
        mw.setWidth( "640px" );
        mw.setHeight( "480px" );
        mw.setBorder( "normal" );
        mw.setTitle( "Some uploaded content" );
        mw.setClosable( true );
        
        Iframe iframe = new Iframe();
        iframe.setWidth( "100%" );
        iframe.setHeight( "100%" );
        iframe.setContent( media );
        iframe.setParent( mw );
        
        mw.setParent( main );
        mw.doModal();
        ]]></attribute>
    </button>
</window>

  -with FF and IE versions prior to 9 everything works as expected
  -with IE9
    -sometimes the iframe will display the uploaded pdf and sometimes not
    -if for whichever reason the iframe remains unloaded it's possible to close the modal (highlighted will do as well as far as this thread is concerned) window and everything works as expected
    -if the iframe correctly shows the uploaded pdf
      -in my equivalent local test I get the famous

GRAVE: Failed to load media, /view/z_i0u/dN2Qp4/4721/1/pannekoek_19190000.pdf
>>org.zkoss.zk.ui.ComponentNotFoundException: Component not found: dN2Qp4
exception
      -when I try to close the modal window the whole page gets cleared

I think this might be related to http://www.zkoss.org/forum/listComment/7612/ and the already solved https://sourceforge.net/tracker/?func=detail&aid=3076384&group_id=152762&atid=785191 bug.

Any suggestion/idea?

With kind regards
