           Summary: Missing Method in AppContext:: getContextName()
           Product: Chameleon
           Version: 2.2
          Platform: PC
        OS/Version: Windows 2000
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Core
        AssignedTo: chameleon-dev at lists.maptools.org
        ReportedBy: uzde083 at syncera.nl


There seems to be a method missing in AppContext to retrieve the param-name of a
parameter: getContextName()
It is a neccessity if you want to walk through all contexts after retrieving the
params by using getContextParams()

Suggested code:

    /**
     * return the name of a context parameter from the parameter's name
     * this is a method the Chameleon class was missing
     *
     * @param szParam the name of the parameter to query
     *
     * @return mixed, the string value or false if not set
     */
    function getContextName( $szParam, $szDefault=false )
    {
        //log entry
        $this->logFuncStart( LOG_VERBOSE, "getContextName( $szParam ) starting" );
        $result = false;

        //implementation
        if ( isset($this->aContext[strtolower($szParam)]))
        {
            $result = $this->aContext[strtolower($szParam)]['param-name'];
            $this->log( LOG_ALL, "$szParam name is $result" );
        }
        else
        {
            // Check all sub context
            foreach ($this->aoContext as $oContext)
            {
                $result = $oContext->getContextValue( $szParam );
                if ($result !== false)
                    break;
            }
        }

        if ($result === false)
        {
            $this->error( 1, "$szParam not found. Returning default name.");
            $result = $szDefault;
        }

        //log exit
        $this->logFuncEnd( LOG_ALL, "getContextName( $szParam  ) done" );
        return $result;
    }
