Acrobat scripting object this.hostContainer is undefined when pdf is in Air

Question

Hi,
I'm attempting to use the Adobe Acrobat hostContainer object
to create a simple interface to allow my Adobe Air application to
move between pages of an embedded pdf doc. However the output I get
indicates that the hostContainer object is undefined. The script
works correctly when the pdf is embedded in a stand-alone html
file, but not in Air.
I have Adobe Acrobat 9.0 and Adobe Reader 9.0 installed. It
does not seem to be an issue with on machines with Adobe 8.0.
My code in the document javascripts of the pdf is as follows:
this.disclosed = true;
if(this.external && this.hostContainer){
try{
this.hostContainer.messageHandler={
myDoc:this,
onDisclose:function(){return true;},
onMessage:function(stringArray){
var cmd=stringArray[0];
try{
if(cmd=="nextPage" &&
this.myDoc.pageNum<this.myDoc.numPages){ this.myDoc.pageNum++;
}else if(cmd=="previousPage" && this.myDoc.pageNum>0){
this.myDoc.pageNum--;
}catch(e){
this.hostContainer.postMessage(
["error thrown in onMessage:",e.message]);
onError:function(e){
this.hostContainer.postMessage(["onError: ",e.message]);
}catch(e){
this.hostContainer.postMessage(["Error thrown in
setup:",e.message]);
}else{
app.alert("unable to set up hostContainer:
this.hostContainer="
+this.hostContainer+" this.external="+this.external);
The output is that the pdf displays correctly then the alert
box pops up with [...]this.hostContainer=undefined
this.external=true.
If anyone has seen this issue or has any ideas it would be
much appreciated.
I've also posted about this problem in the Acrobat Scripting
forum with no solution as yet.
Thanks,

It seems that this issue was registered one month ago into the bug tracking system:
http://bugs.adobe.com/jira/browse/FB-16281?page=com.atlassian.jira.plugin.system.issuetabp anels:comment-tabpanel
Any update / workaround / planning so far ?
The only solution I found is to use version 8.1.3 of the reader.
