[ka-Map-users] Can the legend be dynamic?

[Paul Spencer]

Hi Enri,

thanks for this.  This change will certainly work.  However, I did
actually intend it to be MAP_INITIALIZED because the code in here should
only be run when switching to a new map file because it destroys the DOM
hierarchy of the entire legend rather than just swapping the image
source.  Looking at the code, a more elegant solution is likely
available and I will probably do it later this afternoon.

Cheers

Paul
