setCenter and panBy dont work in zoom_changed handler

[Ivan Abragimovich]

Hi, all.
I found strange behavior of 'setCenter' and 'panBy' function.
When i add event handler to 'zoom_changed' event, something like this:

google.maps.event.addListener(map, 'zoom_changed', function() {
map.panBy(300, 300);
});

Code above doesn't work.
But if I use 'setTimeout' function like this:

google.maps.event.addListener(map, 'zoom_changed', function() {
setTimeout(moveMap, 10);
});

function moveMap() {
map.panBy(300, 300);
}

This code works fine.
Could anybody explain me, why first code snippet doesn't work?

P.S. Sorry for my terrible English.

Lots of things happen asynchronously in v3.
Using a short setTimeout puts your code in the execution queue behind
map workings, rather than getting executed immediately ahead of the
map workings associated with whatever caused the zoom change.

Thank you for explanation:)

Of course it's very pure, but it's enough.

use the idle event instead of zoom_changed, this works perfectly for
me (without timeouts...)
