Hi,<br>
<br>
I think i found a bug in the zoomTo Method of the map, while
investigating an issue in geoext 2 (
<a href="https://github.com/geoext/geoext2/issues/205" target="_blank">https://github.com/geoext/geoext2/issues/205</a>).<br>
The problem seems to be introduced since OL 2.13 and is also
occuring in 2.13.1:<br>
<br>
When you zoom the map with the zoomTo Method multiple times in a
row, the result will be confusing.<br>
To be exact, it will not be the last zoomValue you have given to the
method, instead it will become e.g. 0.<br>
<br>
Here is the simple code which i used to test the behaviour:<br>
<br>
m = map;<br>
m.zoomTo(1);<br>
m.zoomTo(2);<br>
m.zoomTo(3);<br>
m.zoomTo(4);<br>
m.zoomTo(5);<br>
m.getZoom();<br>
<br>
The result of the last line should return a value of 5. But since OL
2.13, it returns 0 or some other non-correct value.<br>
I checked this with the official examples of OL 2.12, 2.13 and
2.13.1:<br>
<br>
<a href="http://dev.openlayers.org/releases/OpenLayers-2.12/examples/all-overlays.html" target="_blank">http://dev.openlayers.org/releases/OpenLayers-2.12/examples/all-overlays.html</a><br>
<br>
In 2.12, everything works as expected, but in<br>
<br>
<a href="http://dev.openlayers.org/releases/OpenLayers-2.13/examples/all-overlays.html" target="_blank">http://dev.openlayers.org/releases/OpenLayers-2.13/examples/all-overlays.html</a><br>
<br>
or<br>

<a href="http://dev.openlayers.org/releases/OpenLayers-2.13.1/examples/all-overlays.html" target="_blank">http://dev.openlayers.org/releases/OpenLayers-2.13.1/examples/all-overlays.html</a><br>
<br>
it does not, like described above.<br>
A first finding is that when you use "zoomMethod: null" on map
instanciation, the problem disappears. So this bug could have
something todo with the "
zoomTween" on the map. Maybe someone could have a detailed look at
this?<br>
<br>
Best regards,<br>
