[OpenLayers-Users] zooming programmatically

[goliah]

Hi Tim

current situation is the following: if I execute map.zoomTo via console
everything seems ok, but if i put it in the code only the overlay size
changes and i get no zoom. Moreover, my overlay gets broken on panning (it
gets displaced).

I tried both putting map.zoomTo after executing map.addLayer(overlay) and
into 'loadend' event for the overlay, but it does not work.

my app is located at
www.maurob.org/webrsa/

an exaple of broken zoom can be reached by clicking on the first button
top-left ("Contesto di riferimento") and then on the second button in the
second row ("Territorio")

regards
Mauro
