Hey all,

I'm working on building a component that allows a user to provision other users into following a record on chatter.

I have a wrapper class with an EntitySubscription obect in it, and a boolean for selection. I then use an apex:inputcheckBox on the vf compnent to enable selection by the user.

Problem is that it does not seem to be selecting...All I'm trying to do with the removeSelected() method below is add the index numbers to a list... It doesnt add anything, and the viewstate never shows any booleans as selected.

Please help.

CONTROLLER:

public with sharing class chatterUtils {

    //This is a specific entity Id to tie a user to via chatter
    public string parentId {get;set;}

    public string index {get;set;}

    public list<userRow> userRows {
        get {
            if (userRows == null) {
                userRows = new list<userRow>();
            }
            return userRows;
        }
        set;
    }

    public class userRow {
       public EntitySubscription rowEnt {get;set;}
       public boolean rowSelected {get;set;}
       public integer rowIndex {get;set;}
       public userRow(EntitySubscription rEnt, boolean rSel, integer rInd) {
           rowEnt = rEnt;
           rowSelected = rSel;
           rowIndex = rInd;
       }
    }

    public list<EntitySubscription> subs {get;set;}

    //Subscribe the list of users to the entity id
    public void provisionFollowers() {
        list<EntitySubscription> sub = new list<EntitySubscription>();
        for (userRow u : userRows) {
            entitysubscription e = u.rowEnt;
            sub.add(e);
        }
        insert sub;
    }

    public chatterUtils() {
        userRows.add(new userRow(new EntitySubscription(parentId = parentId), false, 0));
    }

    public void add() {
        userRows.add(new userRow(new EntitySubscription(parentId = parentId), false, userRows.size()));
    }

    //Remove the clicked row, and set the following indexs back by one
    public void remove(){
        userRows.remove(integer.valueOf(index));
        for (integer i = integer.valueOf(index); i < userRows.size(); i++){
            userRows[i].rowIndex -= 1;
        }
    }

    public list<integer> selectedIndexes = new list<integer>();
    public pageReference removeSelected(){
        for (integer i = 0; i<userRows.size(); i++){
            if (userRows[i].rowSelected) {
                selectedIndexes.add(i);
            }
        }
        return null;
    }
}
