Display only one unit on ScaleLine

[openlayers]

I've created Scaleline like this:

new OpenLayers.Control.ScaleLine({bottomOutUnits:'',bottomInUnits:'',maxWidth:150} )

to display km only. Work fine on FF2.0.0.13 (winXP) but map don't load anymore on IE6/7.

I don't know if this usage of Scaleline is "legal" but it could be cool to display only one unit.

I am seeing this as well, it bombs out in IE in scaleline.js at line 191 at

this.eBottom.style.width = Math.round(bottomPx) + "px";

bottomPx is NaN when the bottom stuff is disabled

I am not sure where i found the documentation on doing it this way, but it is supported in Draw function

Zak:

Can you make a patch that doesn't just display the whole file as changed? really hard to review that way...
