[Chameleon] Billingual method of selecting map file?

[Ken Sanderson]

So far it seems to work fine. The status on layers wont work for
differently named layers, but any layers that are named the same in both
will take on the appropriate status. The extents remain when you switch
languages. Anything specific I should test?

Using the language-sensitive metadata is a great idea though, don't even
need two legend templates just put in a switch to grab the appropriate
metadata attribute. This way I don't need to maintain two MAP files.

I'll jump in here.  This approach may not work in an situation where the

user can switch languages on the fly because Chameleon caches the map 
state by saving copies of the map on each page load.  This has the nasty

side effect of it not actually using the map file that you specify 
except for the first time the app starts - there may be some code in 
there that detects if the map file name has changed, and reset the 
session cached map file, but this would lose the current state 
(extents/layer visibility).

An alternate solution would be to use language-sensitive metadata for 
naming layers and have the two app templates refer to different html 
legend templates.

Just a thought ...
