<tr:iterator> is not adding row count for <tr:message> with trinidad jars.

[kaushalendra jadon]

Issue: Facing issue on screen where we are using <tr:message> element within the <tr:iterator> element. Here as per the 6.3 trinidad jars we are seeing message id is regenerated as "<containerid>:<rowcount>:<messageid>", but in 6.8 trinidad jars message id is regenerated as
"<containerid>:<messageid>" .

Below the actual generated ID with latest trinidad jars.
id=”closingCostsFeeIterator:paidOutSideClosingMsg”
But as code is expecting : id=”closingCostsFeeIterator:1:paidOutSideClosingMsg”

Here when we are trying to get the element using
document.getElementById('closingCostsFeeIterator:'+rowCount+':'+'paidOutSideClosingMsg') its returning null and hence flow breaks.

Code Snippet :
==========================================================================================

<tr:iterator id="closingCostsFeeIterator" value="xxxx" var="closingCostsFeeList" rows="0">
<tr:message messageType="error" id="paidOutSideClosingMsg" styleClass="errorMessage"
inlineStyle="display:none" message="yyyyy">
</tr:message>
</tr:iterator>
