It is blowing up on your lead.concatinate_name_and_email__c field being nul:

 

Try this instead:

 

      if (lead.concatinate_name_and_email__c != null) {    
          Lead newLead = mapLead1.get(lead.concatinate_name_and_email__c.TOLOWERCASE().TRIM());
           SYSTEM.DEBUG('*************mapLead1************************'+mapLead1);
             SYSTEM.DEBUG('@@@@@@@@@newLead@@@@@@@@@@@@@@@'+newLead);
            newLead.addError('already exists<a style=color:GREEN href=/apex/leaderror?id='+LEAD.ID+'>'+  lead.name + '</a>');
      }

Hi. Thanks for your reply. Had you worked on Contact share.please see why it is not working

 

public class Contacterrorclass {

  

public PageReference AssignPermissionforcontact() {
        return null;
    }

public list<user> u{get;set;}
id contactid;
public Contacterrorclass()
{
 contactid=ApexPages.CurrentPage().getParameters().get('id');
 }
   public PageReference AssignPermissionforcontacts() {
       
 
 
 Contactshare cs = new ContactShare(ContactAccessLevel='edit', ContactId=contactId, userOrGroupId=UserInfo.getUserId());

 system.debug('*****************************'+contactId);
  system.debug('____________________________'+cs);
 
 
 pagereference p1=new pagereference('/'+contactid);

return p1;

 
}
}

 in sufficient previlages error is coming.please try to solve this,

Sld.New,

Can you post the line on which you get the permissions error? Are you running this as a standard user or sys admin?
