List has no rows for assignment to SObject

Hi All,

 

I try to send the param from Visualforce page to my controller I just want to deleted my record from list

 

 

List has no rows for assignment to SObject

Error is in expression '{!removePayment}' in component <apex:page> in page welcomecustomerportal


An unexpected error has occurred. Your development organization has been notified.

 

My Visualforce Page:

<apex:repeat value="{!lstAuthContacts}" var="AC">
  <apex:outputField value="{!AC.Name}"/>
  <apex:outputField value="{!AC.Contact_Type__c}"/>
   
  <apex:form>
   <apex:commandLink value="Remove" action="{!removeContact}">
    <apex:param name="delContact" value="{!AC.Id}" assignTo="{!cParam}"></apex:param>
   </apex:commandLink>
  </apex:form>

 

My Controller:

 

public class AccountProfileController {

    public list<Contact> lstAuthContacts{get;set;}
	public AccountProfileController(){
		getlstAuthContacts();			
	}    
	public void getlstAuthContacts(){    	
    	lstAuthContacts = [Select	Contact.Id,
                                        Contact.Name,
                                        Contact.Contact_Type__c,
                           From	        Contact
                           Where	Contact.AccountId = ::ApexPages.currentPage().getParameters().get('id')
                           And		Contact.Contact_Type__c = 'Authorized Contact'];
    	
    }

    public string cParam{get; set;}
    public PageReference removeContact(){
    	if(cParam != null || cParam != ''){
        Contact contact = [select Id from Contact where id=:cParam];            
        delete contact; 
    	}else{
    		system.assertEquals('removeContact', 'ContactId = '+cParam);
    	}    
        return null;
    }    
}

public class AccountProfileController {

        public list<Contact> lstAuthContacts = new list<Contact>();

	public AccountProfileController(){	
	}  
  
	public list<Contact> getlstAuthContacts(){    	
    	lstAuthContacts = [Select	Contact.Id,
                                        Contact.Name,
                                        Contact.Contact_Type__c,
                           From	        Contact
                           Where	Contact.AccountId = :ApexPages.currentPage().getParameters().get('id')
                           And		Contact.Contact_Type__c = 'Authorized Contact'];
       return lstAuthContacts ;    	
       }

    public string cParam{get; set;}
    public PageReference removeContact(){
    	if(cParam != null || cParam != ''){
        Contact contact = [select Id from Contact where id=:cParam];            
        delete contact; 
    	}else{
    		system.assertEquals('removeContact', 'ContactId = '+cParam);
    	}    
        return null;
    }    
}

Your code looks fine except for this one condition check,

 

if(cParam != null || cParam != ''){

 

Make it  - if(cParam != null && cParam != '')

 

Reason - If at all there's no parameter sent from the page, it can be blank or null and in either case you should not be querying. Rest all looks fine to me.

HI apple_sae

 

iam new one to apex and visualforce i tried  your code but it showing error like

 

ErrorError: Compile Error: unexpected token: 'From' at line 12 column 27

how this code solve please help me?

Hi, Sfdc@Smitha

 

Please shoe me your query, I'm not sure may be you for got to put a symbol like :

 

 Contact contact = [select Id from Contact where id=:cParam];

 

 
SLockardSLockard

That's because there is an extra comma in there. Try changing the query to this:

 

lstAuthContacts = [Select	Contact.Id,
                                        Contact.Name,
                                        Contact.Contact_Type__c
                           From	        Contact
                           Where	Contact.AccountId = :ApexPages.currentPage().getParameters().get('id')
                           And		Contact.Contact_Type__c = 'Authorized Contact'];
