[OpenLayers-Users] setCenter zooming problem.

[Christoph Boehme]

Hi,

I had the same problem when I loaded the location and zoom level from a 
cookie. It turned out that the problem was caused by the cookie 
(obviously) returning string values. The zoom-in code in OL contains a 
line which computes zoomLevel+1 which works fine for numbers but results 
in concatenation if zoomLevel is a string. After making sure that 
setCenter receives the zoom as a number (with Number(zoom)) it was 
working fine.
