[mapguide-users] Call legend palette method from scriptFrame

[Kenneth Skovhede, GEOGRAF A/S]

I am not quite sure what you want to do.
If you call SetScale on the legend, it will display the legend as if the 
map was in that scale.
That is probably not what you want.

Javascript is case sensitive, you must use GetLegendCtrl(), not 
getLegendCtrl().

I can only recommend that you install FireFox and the FireBug plugin.
With firebug, you can set breakpoints in code, and examine objects (ea. 
list all avalible functions on a given object):

(PS: You will need a FireBug beta for FF3: 
http://getfirebug.com/releases/firebug/1.1/firebug-1.1.0b12.xpi)
