Issue with Retrieving Previous value.

Content

Hi Team,

We have a custom PHP that sends out a mail when severity of an incident is changed. When we try compiling the code , we are unable to retrieve the previous value of the severity to compare it with the current severity value.

We are executing the CPM synchronously.

Error Thrown :   Line 31 : Trying to get property of a non object

Code Snippet

             <?
/*
 * CPMObjectEventHandler: mailonseveritychange_syn
 * Package: RN
 * Objects: Incident
 * Actions: Update
 * Version: 1.2
 */
use \RightNow\Connect\v1_2 as RNCPHP;

use \RightNow\CPM\v1 as RNCPM;

class mailonseveritychange_syn
        implements RNCPM\ObjectEventHandler
{
    public static function apply( $run_mode, $action, $incident, $cycle )
    {
        if ($cycle !== 0) return;

		
		 if (RNCPM\ActionUpdate == $action)
		 {
	  $incidentId=$incident->ID;
	  
	   $Severity = RNCPHP\ROQL::query("select severity.lookupname from incident where id=$incidentId;" )->next();
	   $SeverityLookupname=$Severity->next();
