That's what happens by default in OpenLayers if nothing is specified for
a projection, ie. it assumes Lat/Lon. The patch I am working on allows
for non-standard projection parameters but in the PROJ.4 initialization
string format, not in the MG WKT format.
Most Fusion widgets don't need projection info in any case. It's only
widgets like the Measure, or CursorPosition widgets where projection
information becomes important.

I know this is neither here nor there, but I believe there are many
valid projections that do not have EPSG codes. Defaulting to LL when
many "non-standard" CS are liner-units-based may not be the best
approach. Would it not be possible to disable coordinate transforms if
there is no code available?

I'm currently working on a patch to retrieve the projection info from
the map definition for MapGuide. The problem is that MG uses WKT and
OpenLayers/Fusion uses EPSG codes and MG doesn't always have an EPSG/WKT
mapping available. So I will be implementing this so that if MG returns
a valid EPSG code it will use that, otherwise it will take a value from
the ApplicationDefinition file, and if there still isn't an EPSG code
available then the projection will be set to the OpenLayers default of
EPSG:4326.

Im trying my hand at some Open Layers programming. I'm trying to set the

Coordinate system to match Mapguides, So I decided to peek into Fusion....
One thing for the life of me I can't find is where fusion sets the
OpenLayer
Maps Coordinate system. I know Open layers uses Proj 4, and Mapguide Can
use
both cs-map and Proj4...I know how to get the coordinate system
Description
out of Mapguide...But how do I push it back into OpenLayers Using my
PROJCS
system...
Or worded Much simpler...How/Where does Fusion do this to openLayers...I
want this to work on anymap...so I don't want to hard code a EPSG code
into
it, and several users will have Non PROJ4 coordinate systems, like Local
County Coordinate systems that CS-MAP allows them to use...
ANYONE?
