           Summary: ROICircle tool can get undefined values in coords
                    parameter
           Product: Chameleon
           Version: 2.2
          Platform: PC
        OS/Version: Windows 2000
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Widget

When you click with the ROICircle tool in the neighbourhood of the map border,
you can get undefined values from the Pix2Geo function.

The Pix2Geo function assumes the X and Y values are inside of the map, but the
following statement in cwc_roi.js (CWCCircleROI_Serialize):

aRadius = this.manager.Pix2Geo( parseInt(this.centerX) + parseInt(this.radius), 
                                                                this.centerY );

can result in breaking this assumption. This results in the following kind of
request:

The image of the ROI is then not consistent with what it should be.
