StreetViewPanorama setVisible bug

[Mel]

In the following code:

<div id="sview" style="width:100%; height:100%"></div>

<script type="text/javascript">

var initialLocation = new google.maps.LatLng(40.760779,
-111.891047); //Salt Lake City
var sview = new
google.maps.StreetViewPanorama(document.getElementById("sview"), {

position: initialLocation,

addressControl: false,

enableCloseButton: false,

linksControl: false,

navigationControl: false,

visible: false });


sview.setVisible(true); //Panorama is properly displayed
...
sview.setVisible(false); //Panorama disappears properly
...
sview.setVisible(true); //Panorama is...still disappeared!

</script>




*Sorry for no link - I discovered this while debugging with a
javascript shell (http://www.squarefree.com/shell/). So I don't
really have a complete example code...

*The bug doesn't show if you do all the setVisible calls in a row -
apparently it has to settle down between each call?

*At the end, sview.getVisible() returns true;

*If sview.setPosition is called at the end, it gets properly displayed
again - but ONLY IF the position being set is different.

*Calling sview.setPov has no effect at the end.

yeah I see it with your test map, and even though the final panorama
has disappeared, it reappears when you use the mouse scroll wheel
(like you said it gets properly displayed if the position being set is
different).

The bug is kinda similar to the following thread:

Okay - yeah, now I see that sview.setPov does have an effect if you
change the zoom.

I've taken the Street View Events example and modified it to display
the Visible property, with a "Toggle Visibility" link to test it, and
it seems to confirm the bug:

I'm experiencing the same bug and I've seen nothing online about how
to fix it yet, but I was able to come up with a temporary hack. By
changing the zoom level of the panorama each time the visibility
property is set to true, the panorama will remain visible (at least in
Firefox).
Ex:
var pov = panorama.getPov();
var cur_zoom= pov.zoom;
if(cur_zoom > 0){
pov.zoom = 0;
}else{
pov.zoom = pov.zoom + 1;
}
panorama.setPov(pov);

panorama.setVisible(true);
