IE8 Applet Issue on ADF

Question

I am having issue with Applet on a .jspx page when using IE8 browser.
I am running on:
JDEVADF_11.1.1.7.0_GENERIC_121026.1729.6438
This blocking our progress at the moment, so any help please.
I created a simple ADF Web Application with a single page that loads an Applet:
+<?xml version='1.0' encoding='UTF-8'?>+
+<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1"+
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:af="http://xmlns.oracle.com/adf/faces/rich">
+<jsp:directive.page contentType="text/html;charset=UTF-8"/>+
+<f:view>+
+<af:document id="d1">+
+<af:form id="f1">+
+<af:commandButton text="commandButton 1" id="cb1"/>+
+<af:switcher id="s1" defaultFacet="true">+
+<f:facet name="true">+
+<f:verbatim>+
+<applet id="MyApplet" name="MyApplet" width="1" height="1" hidden="true"+
scriptable="true" pluginspage="http://java.sun.com/javase/downloads/ea.jsp"
code="com.oracle.HelloWorld"
archive="/Application23-ViewController-context-root/MyApplet.jar"
cache_archive="MyApplet.jar" cache_version="11.1.7.0"/>
+</f:verbatim>+
+</f:facet>+
+</af:switcher>+
+<af:commandButton text="commandButton 2" id="cb2"/>+
+</af:form>+
+</af:document>+
+</f:view>+
+</jsp:root>+
I found that the behavior is different on IE8 and IE9:
on IE9:_
The page was rendered and Applet was loaded.
Clicked on the button and I could see the page refresh.
Clicked refresh on the browser and the page refreshed correctly.
on IE8:_
the page was rendered and Applet was loaded.
Clicked on the button and nothing happened.
Clicked refresh on the browser and it took me to a different URL.
I have tested on Firefox and Chrome and they were fine.
I also tested loading applet using HTML file (not ADF app) and it was fine in IE8.
Hence, this seems to be an ADF specific issue.
any suggestions or idea?
Is there any ADF specific way to load an Applet?

Hi,
you are sitting on an Oracle internal build of JDeveloper. So can you verify the behavior with a public release (JDeveloper 11.1.1.6) to ensure its not an issue with a non-production build? Note that the OTN forum is a public forum and not meant to address Oracle internal builds.
Something to check:
- Is IE8 running in native mode or in compatibility mode (please check the same for IE9)?
- If Applet caching is disabled, does it make a difference?
- If you removed the af:swicther tag surrounding it, does it make a difference?
