           Summary: [Chameleon - Widget] Modify MapDHTML to allow widgets to
                    supress submit on navigation
           Product: Chameleon
           Version: 2.0
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Widget
        AssignedTo: chameleon-dev at lists.maptools.org
        ReportedBy: pspencer at dmsolutions.ca


As written, the MapDHTML widget automatically submits the page as the user
navigates.  Several widgets need to supress this behaviour in order to function
correctly, including the PanMap, Ruler, Query, MapNotes, MapTips and ROI
widgets.  In each case, a widget-specific exception is required in the MapDHTML
widget code.

Proposal is to add the ability for widgets to control page submission without
requiring changes to the MapDHTML widget.  I will add a new form variable,
NAV_SUBMIT, with a default value of "1".  For widgets (such as those listed
above) that do not want the page to be submitted by the MapDHTML widget, they
can set this form field to "0".
