trigger after update lookup field not updated?

trigger countingof on lead (after insert,after update,after delete)
    {
    set<id>  conId = new set<id>();
    map<id,list<lead>> countle= new map<id,list<lead>>();
    
  
 
    
         if(trigger.isafter && trigger.isinsert || trigger.isUpdate )
             {
              for(lead c: trigger.new)
                  {
                   if(c.owner_type__c!=null)
                       {
                       conId.add(c.owner_type__c);
                       }
                  }

                    }
                 }
             }
 
list<lead> leadlist= [select id ,owner_type__c  , no_of_lead__c  from lead where owner_type__c In :conId];
      for(lead a :leadlist)
         {
          countle.put(a.owner_type__c, leadlist);
         }

HI Deepak,

You are getting trapped in recursive trigger, where your trigger is updating again and again.

To overcome this situation you need to create separate static class like this : 

  
public Class checkRecursive
{
    private static boolean run = true;
    public static boolean runOnce(){
    if(run){
     run=false;
     return true;
    }else{
        return run;
    }
    }
}

And your trigger would be like this :  
trigger countingof on lead (after insert,after update,after delete)
{
    set<id>  conId = new set<id>();
    map<id,list<lead>> countle= new map<id,list<lead>>();
    
	if (trigger.isafter && trigger.isinsert || trigger.isUpdate )
	{
		for(lead c: trigger.new)
		{
			if(c.owner_type__c!=null)
			{
			   conId.add(c.owner_type__c);
			}
		}
	}
	if (trigger.isafter && trigger.isDelete)
	{
		for(lead c:trigger.old)
		{
			if (c.owner_type__c!=null)
			{
				conId.add(c.owner_type__c);
			}
		}
	}

	list<lead> leadlist= [select id ,owner_type__c  , no_of_lead__c  from lead where owner_type__c In :conId];
	
	for(lead a :leadlist)
	{
		countle.put(a.owner_type__c, leadlist);
	}
 
	list<lead> lst=new list<lead>();
	list<lead> countlist = [select id, no_of_lead__c,owner_type__c  from lead where owner_type__c in :conId];
      
	for(lead a : countlist)
	{ 
		list<lead> lstt=countle.get(a.owner_type__c);
		a.no_of_lead__c= lstt.size();
		system.debug('@@@a' +a);  
		if(a.owner_type__c!=null)
		{   
			lst.add(a);
		}
    }
	
    if(checkRecursive.runOnce())
    {
        update lst;          
    }
}

Hey Deepak ,

Can you explain your requirment with bit clarity .What is owner_type__c here ? owner_type__c  can not be duplicate in lead ?
You are updating no of lead in lead object it self is it your requirment ?
Please explain so that we can help you .
Thanks
Manoj

@jetha sf not working.
@manoj ji
1-owner_type__c  is lookup of contact. 2-no_of_lead- size of lead in a contact.
after insert and after delete both are working but when i change the owner_type__c  then showing error.
