[X3D-Public] X3D + AJAX3D : addBrowserListener not alwaysworking

That Vivaty API should be rock-solid

You have a VERY old Vivaty player. Please try getting the latest. It should be stable for most X3D content. If you are having problems on your content please email developers at vivaty.com

Thanks. We will try it. But the performance in flux is quite low. And  
more important, flux looks is dead (at least as far as I know) so it 
does not seem the better option.

The code is the base of AJAX 3D, taken from Ajax3d examples 
(http://www.ajax3d.org/content/t3/indexa.html), done by Tony Parisi some 
years ago.

The core code is this:

------------------------------------------------------

function initAjax3d(filename) {

   browser = null;
   context = null;
   listenersSetup = false;

   //browser = document.FLUX1.getBrowser();
   browser = document.getElementById('FLUX1').getBrowser();
     if (browser != null) {
       listener = new Object();
       listener.browserChanged = browserChanged;
       browser.addBrowserListener(listener);

       if (filename != null) browser.loadUrlS(filename);
       else context = browser.getExecutionContext();
   }  }

function browserChanged(evt) {

   if (evt == 0) // BROWSER_INITIALIZED
   {
       context = browser.getExecutionContext();
             setupListeners();
   }
}

-------------------------------------------------------------------

Is suposed browserChanged(evt) should execute each time the scene is 
loaded.

I have used a "not-very-elegant" solution to solve the problem, but I 
prefer to avoid it. I wanted to know if it was just our problem or it 
was something general.

Thanks again!!
