Applet teardown by itself in af:popup in firefox3

Question

this only happens in firefox3 ,no problem in ie and chrome.
and this issue really agonize me a lot. i really appreciate any help!!
the code just like this:
<af:popup id="popup" contentDelivery="lazyUncached">
<af:panelWindow id="pw1">
<f:verbatim >
<applet height="50px" width="100px" archive="audio.jar"
id="applet" name="applet" code="" codebase="" mayscript="true">
<param name="test" value="111"/>
</applet>
</f:verbatim>
</af:panelWindow>
</af:popup>
<af:commandImageLink text="pop" id="gil0" partialSubmit="true">
<af:showPopupBehavior popupId="::popup" triggerType="click"/>
</af:commandImageLink>
after click the commandImageLink ,popup shows and applet starts, but in FF3, applet will be destroyed quickly. any ideal???
thanks!!!

Answer 1

in the Java console,it shows the applet is destroyed. no error trace found there.
seems the space for applet in the UI disappears, then the applet instance is destroyed by java plugin.
through firebug, there will be an uncaught js error thrown.
uncaught exception: [Exception... "Component is not available"  nsresult:   "0x80040111 (NS_ERROR_NOT_AVAILABLE)"  location: "JS frame ::   http://127.0.0.1:7101/LTWeb/afr/partition/gecko/default/opt/boot-11.1.1.3.0-0084.js  :: anonymous :: line 4524"  data: no]
this js exception is thrown from adf face internal js which is only for Mozilla based (gecko rendering engine) browsers.
is this maybe a adf bug for firefox3?
