[OpenLayers-Users] Controls not working

[Frédéric Junod]

Hi,

You can't use the ScaleLine control because you're using and old version of
OpenLayers (http://www.openlayers.org/api/OpenLayers.js version 2.5). The
ScaleLine control was added after the 2.5 release.

You have to use a more recent version of OpenLayers, the new stable release is
not ready yet but you can use the release candidate:
http://openlayers.org/api/2.6-rc1/OpenLayers.js
But this is not the final code !! When the final 2.6 will be released this url
will become obsolete ...
