[OpenLayers-Dev] PanZoomBar doesn't handle forceFixedZoomLevel correct

[Marc Jansen]

Hi Fabian,

thanks for the catch and the patch.

It was me that provided the forceFixedZoomLevel-patch in the first place 
(see http://trac.openlayers.org/ticket/2288) and it was (at least by me) 
never intended to show the behaviour you describe. Could you please add 
tests to your ticket (http://trac.openlayers.org/ticket/2725) that fail 
without your patch and pass with your patch applied?

Thanks in advance and best regards,

Marc

PS: I am pretty sure you should leave the "Assigned to:" field in the 
trac empty so that a core developer can review (and eventually commit) 
your changes.
