JavaScript Problem with Embedded Reader

[Maik_Schulze@adobeforums.com]

Hello,

I've been working on a Browser-based application that lets an embedded Reader (through document JS code) communicate with Flex objects.

This works perfectly as long as I do not load another PDF file. This is how I do it. The Embedded Reader is placed on the HTML site like this:

object id="PDFObj"
NAME="PDFObj"
data="3dobject1.pdf"
type="application/pdf"
width="100%"
height="100%"/

After some time, I would like to load another PDF into the Embedded Reader like this (called upon a button click):

var pdf = document.getElementById("PDFObj");
pdf.data = "3dobject2.pdf";

Unfortunately, JavaScript will not work properly anymore after loading another file. Most of the time, the PDF receives messages from outside and reacts accordingly, but the other direction will not work. The PDF cannot send messages to the HTML site it is embedded in (and therefore not Flex). Sometimes, neither way works.

Does someone have experience with that? Is it because, I implicitly load a new file by setting the data property? Is there a more elegant way to explicitly load a new file into an Embedded Reader? Could this be an issue of the Browser's JavaScript engine? Or a bug in the Embedded Reader? Or is there a JS function that will allow the Browser to properly update the embedded objects? I'm quite out of ideas.

My configuration:
Firefox 3, Windows XP 32 Bit, Acrobat Reader 9.0
Website objects:
PDFs include embedded document JS code and 3D annotations
Flex 3.0

Regards
Maik

What you are doing has NOTHING to with Reader - you are working entirely with the browser...

Hello,

I've not been taking into account that it is not sufficient to change the src attribute. Of course, that will load another PDF. Yet it will also mess up the existing registered msgHandlerObject (inside the HTML). Obviously, it has to be re-initialized. The JS communication will then work again.

I'm sorry for taking your time and being too blind to realize that right away.
