trigger preventingdeletion on Apple__c (before delete) {

  for(Apple__C a:[select id,name,(select id from Orange__r ) from Apple__C where id in:Trigger.oldmap.keyset()]){
   if(a.Orange__r!=null&&a.Orange__r.size()>0){
    Apple__c actualRecord = Trigger.oldMap.get(a.Id);
   actualRecord.adderror('dont delete');
   }
   }

}

I have a trigger that prevents deletion of parent record if child exists ...here my parent object name is Apple__c......,my child object api name is Orange__c....sohere i wrote a trigger on parent object

trigger preventingdeletion on Apple__c (before delete) {

  for(Apple__C a:[select id,name,(select id from Orange__r ) from Apple__C where id in:Trigger.oldmap.keyset()]){
   if(a.Orange__r!=null&&a.Orange__r.size()>0){
   a.adderror('dont delete');
   }
   }

}


The above one is my trigger .....here the problem is trigger saved but its not showing the desired validation error message 

its showing the below error while deleteing the parent record its showing below error ....but my error message in trigger is "dont delete"


There were custom validation error(s) encountered while saving the affected record(s). The first validation error encountered was "Apex trigger preventingdeletion caused an unexpected exception, contact your administrator: preventingdeletion: execution of BeforeDelete caused by: System.FinalException: SObject row does not allow errors: Trigger.preventingdeletion: line 5, column 1".


how to solve this thanks.

I have 2 objects 1 is Trig1__c,second one s Trig2__c......in Trig1__C i have a numberfield called No_of_Trig2__c(Numberfield)....so here what i need is if i enter the 10 in No_of_Trig2__c then 10 records should be created autometically in Trig2__c,......so here is my trrigger

trigger Cretaingrecontrig2 on Trig1__c (after insert) {
  List<Trig2__c>Listtri=New List<Trig2__C>();

  for(Trig1__c tr:Trigger.new){
        if(Trig1__c.No_of_Trig2__c!=null){
        for(integer i=0;i<Trig1__C.No_of_Trig2__c;i++){
            Trig2__c tri=New List Trig2__c();
            tri.id=tr.id;
            tri.Name=tr.Name;
        Listtri.add(tri);
  }
  if(!Listtri.Isempty()){
  insert Listtri;
  }
  }
  }
  }



so here the trigger is saved fine ...but the problem is while saving the record am getting below error
