Adil_SFDC,

 

Before refering to the 0th index of list you must perform a check on whether the list is empty or not.

Adil_SFDCAdil_SFDC

Hi Rahul 

 

i was waiting for the reply . Here there are no records my list is totally empty. 

If my list is empty how do i check this. 

Rahul SharmaRahul Sharma

Whenever you try to access records from list first check if its empty or not like it is done below:

 

List<Account> lstAccount = new List<Account>();

// Fill the list...

// Before processing the list check if its empty or not
// It will go inside the loop only if the List is having values in it. if(lstAccount.size() > 0){ // Do something with lstAccount[0].Name }

 

Adil_SFDCAdil_SFDC

when i try to fill the list i get the error again . I m trying this

 

List< Contact_Email__c> lstcon = new List<Contact_Email__c>();
lstcon[0].subject__c= ' ';
insert lstcon;
if(lstcon.size()>0){
if(isDynamic == 'true'&&lstcon[0].subject__c==null)

 

I get error again

Rahul SharmaRahul Sharma

In your code just add a condition and check if it helps:

if(isDynamic == 'true' && ce.size() > 0 && ce[0].Subject__c==null )

 In previous post it was just an example to explain when to add the check.

Adil_SFDCAdil_SFDC

i Added this  and it works

 

List< Contact_Email__c> lstcon = new List<Contact_Email__c>();
Contact_Email__c cont = new Contact_Email__c();

cont.subject__c= ' ';
lstcon.add(cont);
if(lstcon.size()>0){
if(isDynamic == 'true'&&lstcon[0].subject__c==null)

Rahul SharmaRahul Sharma

Yup that would work too..

Adil_SFDCAdil_SFDC

Hi Rahul that works but my select title fails 

I dont get any error message but the select title doesnt pass in the endpoint. 

Any suggestion

Rahul SharmaRahul Sharma

Add some debug statements for knowing the cause.

Adil_SFDCAdil_SFDC

I get error 

 

Arguement 1 cannot be null in test method. 

 

any solution for this
