[SalesForce] Link New Contact and Account from Live Agent Pre-Chat form sample

I am working with the Live Agent Developer Guide Pre-Chat Form code sample and have modified it to include a pre-chat form field for the Account name. I am able to use the sample code successfully to create the contact, case, and account and link the contact, case, and account to the live agent transcript and link the contact and account to the case with the supplied defaults.

Where I am having difficulty is for the condition when a match is not found by email and the form data is used to create a new contact/account, I am not having success linking the new contact to the new account that is created. I've tried modifying the findOrCreate.map and findorcreate.linkToEntity methods but have not had success. There is a note when using the findOrCreate.linkToEntity method that:

You can only link records if the parent record is created with a findOrCreate API call. You can’t link a child record to a record you found using the findOrCreate.linkToEntity method.

Even so, I am not certain this is the case in the below code sample.

Any suggestions to help link the new contact to the account would be awesome.

<apex:page showHeader="false">

    <!-- This script takes the endpoint URL parameter passed from the deployment page and makes it the action for the form -->
    <script type='text/javascript'> 
(function() { 
function handlePageLoad() { 
var endpointMatcher = new RegExp("[\\?\\&]endpoint=([^&#]*)"); 
document.getElementById('prechatForm').setAttribute('action',
decodeURIComponent(endpointMatcher.exec(document.location.search)[1].replace("javascript:", "")));
} if (window.addEventListener) { 
window.addEventListener('load', handlePageLoad, false); 
} else { window.attachEvent('onload', handlePageLoad, false); 
}})(); 
</script>
