I have the controller below for a Visualforce page set up on the Contact record as a Detail Page button. The purpose is to allow users to set up multiple tasks at once, but also pre-populate the WhoID, OwnerId, and WhatId for the tasks.

The problem I am running into is when I click the Add Another RDA button on the VF page, it creates an exact clone of the previous task and if I change a value, it changes for all the tasks. How can I make it so that each task is individual of one another, but still able to be created at the same time?


public with sharing class RDATasks{

    public list<Task> listTask{get;set;}

    private final Contact con;
    public RDATasks(ApexPages.StandardController myController){
        listTask = new List<Task>();

    public Task task1 = new Task();
        public void RDA(){
            Task1.WhoId = con.Id;
            Task1.OwnerId = UserInfo.getUserId();
//            Task1.WhatId = con.AccountId;
            Task1.RDA__c = TRUE;

    public PageReference saveTask(){
        insert listTask;
            PageReference contactPage = new PageReference('/' + con.Id);
            return contactPage;


<apex:page standardController="Contact" tabStyle="Contact" sidebar="false" extensions="RDATasks" action="{!RDA}">

<apex:form >

<apex:sectionHeader title="Activities"/>
<apex:repeat value="{!listTask}" var="tsk">
    <apex:pageBlock >
        <apex:pageBlockSection >
            <apex:outputField value="{!Contact.Account.Name}" label="Related To"/>
            <apex:outputField value="{!Contact.Name}" label="Name"/>
            <apex:inputField value="{!tsk.Type_of_RDA__c}" style="width:35%"/>
            <apex:inputField value="{!tsk.Subject}" style="width:45%"/>
            <apex:inputField value="{!tsk.ActivityDate}" style="width:35%"/>
            <apex:inputField value="{!tsk.Status}" />
            <apex:inputField value="{!tsk.Description}" style="width:100%"/>

    <apex:commandButton value="Add Another RDA" action="{!RDA}"/>
    <apex:commandButton value="Save RDAs" action="{!saveTask}"/>

Don't share a reference.


As written, every time you add a "new record", you're just manipulating the same reference to task1.

Task task1 = new Task();
public void RDA()
    task1.WhatId = con.Id;
    // other fields;


Instantiate a new Task record each time you call the method, and the references will not be shared.

public void RDA()
    Task record = new Task();
    record.WhatId = con.Id;
    // other fields

More efficient

You don't even have to cache the record at all, and can specify field=value pairs in the constructor, which is significantly faster.

public void RDA()
    listTask.add(new Task(
        WhoId = con.Id,
        // other fields
  • Awesome, thanks so much!! Do you know how I would build in the ability to remove a task after calling the RDA method, in case a user changes their mind about creating it? Jan 18, 2017 at 21:49
  • That would be a separate question. :) If you have a UI to create new records and you want to remove one of them, you'll need to use a list and remove by index, likely. I recommend you do a bit of research and make an attempt, then post here (as a new question) if you get stuck.
