Permalink.html

Revision 7986, 11.7 kB (checked in by euzuro, 4 months ago)
Fix for Permalink's override-able createParams() function, which was designed to allow for input parameter values for center, zoom, and layers... but was actually only using the center value... zoom and layers were being taken from the map and the input parameters ignored. Big thanks to our anonymous poster for spotting this. r=ahocevar (Pullup #1489)
