Passing Visualforce InputField to Controller

Question

This is probably a simple fix, but I'm struggling. I have a VF page that pre-populates Task fields via a controller extension. I want to then give the user the option to create a follow-up task. I want this task to duplicate some of the fields entered by the user in the initial task (e.g., subject, due date + 7 days, etc.). Can anyone help. Thanks

Controller:

public with sharing class RDATasks{

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

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

//  Adds Task to list
    public void RDA()
    {
        listTask.add(new Task(
           WhoId = con.Id,
           Status = 'Completed',
           ActivityDate = system.TODAY()+7,
           OwnerId = UserInfo.getUserId(),
           WhatId = con.AccountId,
           RDA__c = TRUE)
           );
    }

//  Adds Follow-Up Task to list
    public void RDAfollow()
    {
        listTaskFollow.add(new Task(
           WhoId = con.Id,
           Status = 'In Progress',
           ActivityDate = system.TODAY()+7,
           Subject = 'Follow-Up: ',
           OwnerId = UserInfo.getUserId(),
           WhatId = con.AccountId,
           RDA__c = TRUE)
           );
    }

//  Saves list of Tasks added
    public PageReference saveTask(){
        insert listTask;
        insert listTaskFollow;
            {
            PageReference contactPage = new PageReference('/' + con.Id);
            contactPage.setRedirect(true);
            return contactPage;
            }
    }
}

VF Page:

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

<apex:form >

<apex:repeat value="{!listTask}" var="tsk">

You can add a show/hide attribute to the <pageBlock id="addedTasks" render="{!myRenderVar}"> in this section of code that's changes value when you initially click the "Save" button to set it to true as shown below. When true, the pageBlock renders, when false, it doesn't. You can set it in your controller or use an action attribute in your Button for "onClick".

<apex:repeat value="{!listTaskFollow}" var="tskF">
    <apex:pageBlock id="addedTasks" render="{!myRenderVar}">
        <apex:pageBlockSection >
            <apex:outputField value="{!Contact.Account.Name}" label="Related To"/>
            <apex:outputField value="{!Contact.Name}" label="Name"/>
            <apex:inputField value="{!tskF.Type_of_RDA__c}" style="width:35%"/>
            <apex:inputField value="{!tskF.Subject}" style="width:45%"/>
            <apex:inputField value="{!tskF.ActivityDate}" style="width:35%"/>
            <apex:inputField value="{!tskF.Status}" />
            <apex:inputField value="{!tskF.Description}" style="width:100%"/>
        </apex:pageBlockSection>
    </apex:pageBlock>
</apex:repeat>

The question then becomes, do you want to keep the follow-up task separate? If not, in your controller, I recommend you consider changing

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

to

public Task taskFollow{get;set;}

since you presumably will only need to create one of these at a time. Once created, you should call a method that adds this follow-up task to your main list of Tasks. If not, you'll need to keep track of the length of listTaskFollow as you add new tasks to it, which brings to me where I suspect you may be having issues with populating follow-up tasks.

You've not said exactly what fields you want to add, but what you'll want to do is create a new Task that uses the fields from listTask[n] where integer n = listTask.size()-1.

Assuming you continue to use listfollowTask:

Set<Task>Tasks = new Set<Task>();
Set<Task>FollowTasks = new Set<Task>();

public PageReference saveTask(){
    insert listTask;
    insert TaskFollow;
    if(!TaskFollow.isEmpty()){
        Tasks.addAll(listTask);
        FollowTasks.addAll(TaskFollow);
        if(!Tasks.containsAll(FollowTasks)){
            integer last = TaskFollow.size();               
            listTask.add(TaskFollow[last];
            // assumes you only allow user to add one follow-up Task at a time
         }

    RDAfollow();
        {
        PageReference contactPage = new PageReference('/' + con.Id);
        contactPage.setRedirect(true);
        return contactPage;
        }

public void RDAfollow()
{
    n=listTask.size() - 1; // assumes you've already declared n as integer
    listTaskFollow.add(new Task(
       WhoId = con.Id,
       Status = 'In Progress',
       ActivityDate = system.TODAY()+7,
       Subject = 'Follow-Up: ',
       OwnerId = UserInfo.getUserId(),
       WhatId = con.AccountId,
       RDA__c = TRUE
       Subject = listTask[n].Subject;
       Comments = listTask[n].Comments; 
       )
       );
}
