Another post for future referencing


Adding error handling within a Trigger or database transaction

try{
}catch(DMLException e){
         for (Integer i = 0; i < e.getNumDml(); i++) {
            // Process exception here
                System.debug(e.getDmlMessage(i));
                LineItemList [i].adderror(e.getDmlMessage(i));
        }

     }



Adding error handling within a method


try{
   //work here
 }catch(exception e){
            ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.FATAL,e.getmessage()));

}
