JSF ui:repeat with render - jsf

Question

I want to use a ui:repeat or any other iterative tag to display a number of components once
for each item in an Array list.
<!-- print multiple mandates -->
<ui:repeat id="mandates" var="mandate" value="#{taxheadDirectDebit.mandates}">
<a4j:region id="remittanceDetailsSection"
rendered="#{(taxheadDirectDebit.accountFinancialInfo.registration.type != 'PREM') or (taxheadDirectDebit.accountFinancialInfo.registration.type != 'VAT')}">
<!-- Remittance Details -->
<fieldset><legend class="sub"> <h:outputText
value="#{msg['remittanceDetails.title']}" /> </legend>
<!-- Estimated Liability -->
<div class="field">
<div class="label"><label for="allocatedAmount"><h:outputText
for="estimatedLiability"
value="#{msg['remittanceDetails.estimatedLiability']}" /> </label><span
class="requiredFlag">*</span></div>
<div class="error">

</div>

I've taken out a lot of my code here so there may be un macthed divs etc but the idea is there.
I have two problems:
You can see that some components have change events that render other components based on id. These don't work inside the repeat
I'm using webflow and adding messages to the message context so that the message tags can display validation messages but these don't work in the iteration either.
I have tried tr:iterator, c:forEach, a4j:repeat, tr:forEach. I'm pretty sure what I'm trying to do isn't possible the way I'm trying to do it so if anyone has experience trying to achieve similar I'd appreciate some help. I can't change the MVC frameowork I'm using but could use perhaps jQuery.

Answer 1

I solved this by moving the ajax region outside the repeat and just calling render on the whole region. Not beautiful I know but the quickest solution I could find.
On the message front I simply add the index of the item in the list being iterated over into the message.
"remittanceDetails:mandates:"+taxhead.getMandates().indexOF(mandate)+":remittanceAmount" + frequency.getMonth().getCode()
JSF looks after the rest.
