 }
}

I want to get the id of account on the current visualforce page so that I can add/delete multiple contacts for that particular account. But I am getting error as Method does not exist or incorrect signature: ApexPages.currentPage.getParameters() Please help me

Answer 1

currentPage is a method of ApexPages and not a property.

change this

ApexPages.currentPage.getParameters().get('Id')

to

ApexPages.currentPage().getParameters().get('Id')

Answer 2

Can you try getting AccountId in Constructor and then use it for passing the parameter so that you will get Id as soon as the page gets Loaded.

try like following:

public class addAttendee {      
  public Id accountIdParam ;

  public addAttendee(ApexPages.StandardController controller) {
     //Store the Id in variable at page Load and use it across the class
     accountIdParam = ApexPages.currentPage().getParameters().get('Id');    
  }

public void addRow(){
 addattendeeList = new List<Contact>();
 attendeeList.add(new Contact(AccountId = accountIdParam));
}

this will make your code more reusable also it should be

ApexPages.currentPage().getParameters().get('Id');

you are missing () in currentPage()
