** UPDATED (Simplified my custom object to no longer be a wrapper within a wrapper) **

Since posting I've made some adjustments, so at the moment I have a custom wrapper object called ShipmentInvoiceLineItem which basically represents 1 of 2 possible custom objects as well as a boolean selected value:

public class ShipmentInvoiceLineItem {

    public Custom1__c c1 {get; set;}
    public Custom2 c2 {get; set;}
    public String accountId {get; set;}
    public String shipmentId {get; set;}
    public Boolean selected {get; set;}

    public ShipmentInvoiceLineItem(Custom1 c1, Boolean selected){
        this.c1 = c1;
        this.accountId = c1.Shipment__r.Account__c;
        this.shipmentId = c1.Shipment__c;
        this.selected = selected;
    }

    public ShipmentInvoiceLineItem(Custom2 c2, Boolean selected){
        this.c2 = c2;
        this.accountId = c2.Account__c;
        this.shipmentId = c2.Shipment__c;
        this.selected = selected;
    }

}

On the front end I have multiple <apex:repeat> fields that iterates through custom maps I created in my controller (this way I could group by Accounts and Shipment types without my previous complex multi-dimensional map object). The issue I'm having is with the actual form within each of these groupings. Within the form I iterate through my wrapper object like so:

<apex:repeat value="{!ShipmentInvoiceLineItemsByShipment[shipment.Id]}" var="item">

Note: ShipmentInvoiceLineItemsByShipment is structured as list of ShipmentInvoiceLineItems indexed by their shipment Id Map<String,List<ShipmentInvoiceLineItem>>

Visually everything appears to be working fine, as expected the boxes are pre-checked (assuming the user will want these to be checked), but when I uncheck any of of the checkboxes and submit it like so:

enter image description here

When I attempt to iterate through the ShipmentInvoiceLineItemsByShipment it doesn't appear to have SET the boolean value to false as expected.

public PageReference markLineItemsAsPaid() {
    // I passed this as a parameter in <apex:commandLink>
    String id = ApexPages.currentPage().getParameters().get('processID'); 
    for(ShipmentInvoiceLineItem lineItem : getShipmentInvoiceLineItemsByShipment().get( id )){
        if(lineItem.selected == TRUE) {
            System.debug('::SELECTED::');
        }
    }
    return NULL;
}

Any ideas of what could be the problem here?

    Well, you initiate selected as TRUE so the real issue is why are they not checked when displayed? Relevant VF page code will be needed. What is your button code? – Eric Aug 25 '15 at 18:59
  • They are checked when displayed, but then I unchecked one so that I can verify I'm only about to UPDATE the selected items – Xtremefaith Aug 25 '15 at 21:20
  • do you have action="immediate" on the Mark as Paid button? that would prevent any of the unchecked line items from invoking the setter for selected. same issue if you are using actionRegions that aren't encompassing enough. The debug log will show each setter getting called with its value – cropredy Oct 20 '15 at 0:57
  • No I don't have that set on any (I read about that as well). Although I just realized that the last iteration of the Shipment Order forms works which leads me to believe that the problem is because of a shared ID, so I tried to add an iteration number to the form like so: <apex:form id="soAccountingForm-{!shipment.Id}"> but got the following error: Error: Literal value is required for attribute id in <apex:form> – Xtremefaith Oct 20 '15 at 1:19
  • The more test I run it appears evident that the issue is with a duplicate form ID, and at the moment I can't find a way to create a dynamic ID for each form based on the <apex:repeat> iteration. Any ideas on that? Pretty sure that would resolve this – Xtremefaith Oct 20 '15 at 1:36

Keep in mind the documentation on <apex:form> states:

"As of API version 18.0, ​this tag can't be a child component of <apex:repeat>"

So, your <apex:form> should be outside of your <apex:repeat>

Then, you should apex:actionRegion tags so that you only have one form tag. With this you can submit the data by region instead of multiple forms as stated here:
