Hi, I try to use a4j:mediaOutput to pre-view objects. However, it does not render object correctly while the html object tag works fine.

<rich:panel id="previewPanel">
 <object data="#{fileUploadBean.uri}" type="text/html" style="width:500px; height:200px;"/>
 <a4j:mediaOutput element="object" mimeType="text/html"
 createContent="#{fileUploadBean.paint}" value="#{row}"
 style="width:500px; height:200px;"
 uriAttribute="#{fileUploadBean.uri}">
 </a4j:mediaOutput>
</rich:panel>

Actually, fileUploadBean.paint method is never called and IE display a red cross for the component. I searched this forum but I did not get a clear answer.

I really want to use a4j:meidaOutput instead of html object tag because I can set element attribute dynamically and use createContent to retrieve data from database.

Any suggestion will be appreciated.
