Well it did work but not consistently. If I alert() the value of this.getZoom() in the zoom_changed listener it gives me the correct value. I save the value in a variable and when I take it out the alert () it doesn't give the correct value. It's like it needs to wait 1 millisecond to actually load the correct value after fitbounds is called. Any suggestions?
