           Summary: cwc_button.js: suppress alert and add null check
           Product: Chameleon
           Version: 2.2
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Core
        AssignedTo: chameleon-dev at lists.maptools.org
        ReportedBy: bartvde at xs4all.nl


The alert is not useful for users and only comes into play when using a widget
with the visible attribute set to false (this can be quite useful when wanting
to use javascript code generated by the widget).

So I propose removing the alert.

    else
    {
        //alert( "image object for " + this.szImageName + " not found?" );
    }

Another null check needs to be added for everything to work again since there
are now buttons in the application without images:

function CWCButton_SetState( nState )
{
    if (!this.oImage) return false;
    ...
