[mapguide-users] multiple extent attributes on a layer

[Andy Morsell]

The way you've defined your layer, since you have more than one style for a
given range, only the top style is going to appear.  For instance, if a user
is zoomed in between 0 and 22000, there are 4 different styles that apply,
which doesn't make sense.  You should instead use the Theme option to create
multiple styles based on multiple conditions within one scale range.
Depending on what you are doing, you may have more than one scale range,
each with its own theme options.

Kori,

Here's a picture of my layer - I've described 4 separate extents.

0-22000 is all roads (except Highways and Ramps) 0-44000 is  Arteries (Class
= 'A') 0-infinity is Class='H' in yellow - highways 0-infinity is Class='R'
in orange - ramps

And - no - once you get down to 22000 - the Highways and Ramps and Arteries
stop displaying.

Please advise,

-- Eric
