           Summary: [Chameleon-Widget] Projection Selection WGS84 produces
                    errors and wrong keymap extent.
           Product: Chameleon
           Version: 1.99
          Platform: PC
        OS/Version: Windows 2000
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Widget

[Chameleon-Widget] Projection Selection WGS84 produces errors and wrong keymap
extent.

I realize setting keymap extent on the fly with the current projection is
difficult, but I think there is a problem.

testing with sample app: http://localhost/chameleon/samples/sample_enhanced.phtml


Issue 1:
At full extent select: WGS84 / LCC Canada

The resulting map is the full extent of Canada where the keymap is shifted
south. I believe there is a calculation issue here with this projection.

Issue 2:
At full extent select: using any WGS84 / ** Projection

I get the error: 
Fatal error: [MapServer Error]: msProcessProjection(): major axis or radius = 0
or not given in D:\ms4w\apps\chameleon\htdocs\widgets\Widget.php on line 618

I thought maybe this was a result of being at the extent of Canada and since UTM
is invalid at that extent, but it occurs at any scale, with any WGS84 projection.


I think this bug should not stop the beta 2 to go out but is important for beta 3.
