If the problem is the “addCallback” doen’t work after a “visibility=hidden”, replace “visibility=hidden” bye “width=0″.

Then it will work !

Good luck!

Everything works until wrapped in form tags, and thought to use solution; window.[flash_movie_id] = document.forms[0].[flash_movie_id];

this is my code;

var flashVideoPlayer;

function _nsStop() {

var isIE = navigator.appName.indexOf(”Microsoft”) != -1;
flashVideoPlayer = (isIE) ? window['videoPlayer'] : document['videoPlayer'];
}
// Call the pauseResume() function within the SWF file.
function callFlashPlayPauseVideo() {
flashVideoPlayer.pauseResume();
}

Thank you so much

In Firefox Addcallback worked like a charm – in i got the message like state in the title “Object doesn’t support property or method”

Searching the web i found many tips and solutions – neither one solved my problem.

My page is set up with a neat little Ajax calls using JQuery.
So there is the solution:

Instead of filling your page with something like

$('#content').html(ajaxResponse);


use the old-fashioned way:

document.getElementById('content').innerHTML = ajaxResponse;


So the whole request / output goes like this

$.ajax({
type: "GET",
url: "myflashplayerTemplate.html"
success: function(ajaxResponse){
document.getElementById('content').innerHTML = ajaxResponse;
}
});


I hope to save someone else’s time with this one

1. Beware ActiveX reserved words, which will obviously only break IE. My problem was that I was registering a callback named ‘play’ – sure enough, a reserved word.

2. When debugging in IE7, be sure to clear the cache by going to tools>Delete Browsing History. Control F5 doesn’t clear the cache of old .swf files like in other browsers.
