Hi,

I wanted to populate a list incrementing myself the meter :

public with sharing class CSR_CORE_RequestTriggers_SendSingleEmail {

// Collections
public list<string> lTypesContactList {get;set;}

public void SendEmail(List<Request__c> closedRequestList){
System.debug('## Start class ## CSR_CORE_RequestTriggers_SendSingleEmail - ligne 14 ' + UserInfo.getName());

	for (Request__c closedRequest:closedRequestList){

// GET EMAIL ADDRESSES
	
	Boolean resultTest;
	
	//put values of multi-select picklist field into a list
		try{
		list<string> lTypesContactList = closedRequest.Contact_types_for_Email__c.split(';', 15);
				
	// for every type of contact of the list, find its email address in Contact external
	     Integer count = 0 ;
	     for (String sTypesContact : lTypesContactList) {
	      	System.debug('valeur de sTypesContact : ' + sTypesContact);
	     
		     try{	
		     Contact_external__c acc_Contact_External  = [select Name, Email__c from Contact_external__c 
			     where Account__c = :closedRequest.Entity__c 
			     and title__c = :sTypesContact limit 1 ];
		     	// it is an external contact
  		 	 	 System.debug('valeur de acc_Contact_External : ' + acc_Contact_External);
		     	 if(acc_Contact_External.Name != null){
		     	 	 // contact has an email address
					 if(acc_Contact_External.email__c != null){
					 	 // System.debug('valeur de count = [' + count + ']');	
					     // lEmailAddressesList.add(acc_Contact_External.email__c); *
					     lEmailAddressesList[count] = (acc_Contact_External.email__c); 
					     count++;
					 }
		     	 }	 
		     } catch (System.QueryException e) {
		     	System.debug('passage dans le Catch');
		     	// not found in external contact
			  	resultTest = sTypesContact.contains('lanner');
	  		 	// is it a planner ?
  		 	 	System.debug('valeur de resultTest - Planner : ' + resultTest);
	  		 	if(resultTest == true ) {
	  		 	
		  		 	Request__c acc_Request = [select Id, Entity__r.Supply_planner_contact__r.Email 
		  		 	 from Request__c where Id = :closedRequest.Id];
					  System.debug('valeur de acc_Request : ' + acc_Request);
					  System.debug('valeur de acc_Request.Entity__r.Supply_planner_contact__r.Email : ' + acc_Request.Entity__r.Supply_planner_contact__r.Email);
					
			  		 	 if(acc_Request.Entity__r.Supply_planner_contact__r.Email != null){
			  		 	 	System.debug('valeur de Planner email : ' + acc_Request.Entity__r.Supply_planner_contact__r.Email);
			  		 	 	// lEmailAddressesList.add(acc_Request.Entity__r.Supply_planner_contact__r.Email); 
					        lEmailAddressesList[count] = (acc_Request.Entity__r.Supply_planner_contact__r.Email); 
					        count++;
			  		 	  }
	  		 	} else {

	  		 	resultTest = sTypesContact.contains('ield Service'); 
	  		 	System.debug('valeur de resultTest - FSM : ' + resultTest);
	  		 		// is it a field service manager ?
		  		 	if(resultTest == true ) {

			  		 	Request__c acc_Request = [select Id,  Entity__r.Field_service_manager_contact__r.Email  
			  		 	 from Request__c where Id = :closedRequest.Id];
						  System.debug('valeur de acc_Request : ' + acc_Request);
						  System.debug('valeur de acc_Request.Entity__r.Field_service_manager_contact__r.Email  : ' + acc_Request.Entity__r.Field_service_manager_contact__r.Email);

					  		 	 if(acc_Request.Entity__r.Field_service_manager_contact__r.Email  != null){
					  		 	 	System.debug('valeur de FSM email : ' + acc_Request.Entity__r.Field_service_manager_contact__r.Email);
					  		 	 	// lEmailAddressesList.add(acc_Request.Entity__r.Field_service_manager_contact__r.Email); 
					                lEmailAddressesList[count] = (acc_Request.Entity__r.Field_service_manager_contact__r.Email); 
					                count++;
				  		 		 }
	  		 		}
		  		 }
		     } // try (1)
	     } // for lTypesContactList
    
    System.debug('valeur de lEmailAddressesList après boucle lecture : ' + lEmailAddressesList);

(I used first .add method, but I add only the last value)

Does anybody can tell me what I am doing wrong ?

Thank you  !
