Access parent object from Controller extension of Apex-based custom list view button

Question

Imagine you want to add a custom button (Apex based, no JS) to the Related Contacts list on an Account detail page. To perform the buttons action you need some information of the parent Account.

Page

<apex:page standardController="Contact" extensions="ContactAction_CtrlExt"   
           recordSetVar="contacts" action="{!doAction}">

</apex:page>

Controller class

public with sharing class ContactAction_CtrlExt {

    private Account account;
    private List<Contact> relatedContacts;


    // CONSTRUCTOR

    public ContactAction_CtrlExt(ApexPages.StandardSetController standardSetController) {
        account = ...???...;
        relatedContacts = (List<Contact>) standardSetController.getRecords();
    }


    // ACTION METHOD

    public PageReference doAction() {
        doSomething(account, relatedContacts);
    }   
}

Is there a way to access the account in the Controller Extension code of your list button?

Do you have a custom visualforce page on the standard account layout or is it a custom button on the stanrad related list? — Sergej Utko

Try to get the ID parameter of the page:

public ContactAction_CtrlExt(ApexPages.StandardSetController standardSetController) {
    String accId = ApexPages.currentPage().getParameters().get('id');
    account = [Select Id, Name From Account Where Id = :accId]:

    relatedContacts = (List<Contact>) standardSetController.getRecords();
}

Here is a simple example. I've created a list view button on the Contact object with Content Source "Visualforce Page". On that page i access the ID parameter:

<apex:page standardController="Contact" tabStyle="Account" recordSetVar="">
    Id: {!$CurrentPage.parameters.id}
</apex:page>

This this exact the Account ID:

@mastOr: As Mohit states the button is not embedded directly on the account page. I am using this technique: andyinthecloud.com/2013/07/16/…

@RobertSösemann So try my solution then. It must work, this only looks so tricky but if you access the ID through ` ApexPages` you will get the ID of the Account :)
