           Summary: [Chameleon - Widget] ProjectionLabel widget doesn't show
                    correct label
           Product: Chameleon
           Version: 2.0
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: minor
          Priority: P2
         Component: Widget
        AssignedTo: chameleon-dev at lists.maptools.org
        ReportedBy: pspencer at dmsolutions.ca


The projection label can show incorrect labels (i.e. it doesn't find a match in
the projection shared resource.  Since this code has been used, unchanged, for a
couple of years, it seems that something may have changed in mapscript's
reporting of the projection string.

Changing the index at which the code looks for the epsg code from 5 to 6 makes
it work.  Inspecting the projection, it seems that the projection is now
reported with a "+" in front of it.  This only happens if you call
'setProjection' on the map object (i.e. if you have a projection defined without
the + then it works until you change projections).

The code for detecting the epsg code is not very robust and needs to be updated
to search for epsg:xxxxx rather than use a fixed offset in a string.
