ajaxCFC data writing to wrong fields

[Stormpool]

I have a customer update form populated by the CFC page, the code for the update button is as follows... (messy I know) - I have tried doing this with a javascript -> coldfusion array but I was getting a dereference scalar error.

<input type="button" value="Update Customer" onclick="updateCustomer(<cfoutput>'#arguments.cst_id#'</cfoutput>, fetchElement('new_title').value, fetchElement('new_firstname').value, fetchElement('new_lastname').value, fetchElement('new_address').value, fetchElement('new_city').value, fetchElement('new_postcode').value, fetchElement('new_phone').value, fetchElement('new_phone2').value, fetchElement('new_fax').value, fetchElement('new_email').value, fetchElement('new_details').value, fetchElement('new_creditlimit').value, fetchElement('new_creditperiod').value, fetchElement('new_creditstop').value, fetchElement('new_discount').value)"/>

the updateCustomer function is as follows

function updateCustomer(cst_id, cst_title, cst_firstname, cst_lastname, cst_address, cst_city, cst_postcode, cst_phone, cst_phone2, cst_fax, cst_email, cst_details, cst_creditlimit, cst_creditperiod, cst_creditstop, cst_discount) {

// send data to CF
DWREngine._execute(_ajaxConfig._cfscriptLocation, null, 'updateCustomer', cst_id, cst_title, cst_firstname, cst_lastname, cst_address, cst_city, cst_postcode, cst_phone, cst_phone2, cst_fax, cst_email, cst_details, cst_creditlimit, cst_creditperiod, cst_creditstop, cst_discount, updateCustomerResults);
}

// call back function
function updateCustomerResults (r) {
// evaluate server side JS
eval(r);
}

If I put an alert(cst_id); etc... I can confirm the correct fields are passed to the function.

But when this code runs through the ajaxCFC stuff it comes out the other end all wrong! the cst_phone is updating the cst_creditlimit etc.. I think it's the ajaxCFC software because I get argument errors if I pass a string through the cst_phone it tells me cst_creditlimit requires numeric. The arguments are in the same order as the javascript function uses.

The beginning of my CFC function is as follows

<cffunction name="updateCustomer" output="no" access="private">
<cfargument name="cst_id" type="string" required="Yes">
<cfargument name="cst_title" type="string" required="Yes">
<cfargument name="cst_firstname" type="string" required="Yes">
<cfargument name="cst_lastname" type="string" required="Yes">
<cfargument name="cst_address" type="string" required="Yes">
<cfargument name="cst_city" type="string" required="Yes">
<cfargument name="cst_postcode" type="string" required="Yes">
<cfargument name="cst_phone" type="string" required="Yes">
<cfargument name="cst_phone2" type="string" required="Yes">
<cfargument name="cst_fax" type="string" required="Yes">
<cfargument name="cst_email" type="string" required="Yes">
<cfargument name="cst_details" type="string" required="Yes">
<cfargument name="cst_creditlimit" type="numeric" required="Yes">
<cfargument name="cst_creditperiod" type="numeric" required="Yes">
<cfargument name="cst_creditstop" type="numeric" required="Yes">
<cfargument name="cst_discount" type="numeric" required="Yes">

Any ideas? thanks.

I've narrowed this down. There appears to be a problem when I get above 10 variables..

The following works as expected.

DWREngine._execute(_ajaxConfig._cfscriptLocation, null, 'updateCustomer', cst_id, 'Miss', 'Anne', 'McCarthy', 'address', 'town', 'postcode', '01386 xxxxxx', '07973 xxxxxx', 'na', updateCustomerResults);

In the following 'test' adds itself before 'Anne' and pushes everything along one field.

DWREngine._execute(_ajaxConfig._cfscriptLocation, null, 'updateCustomer', cst_id, 'Miss', 'Anne', 'McCarthy', 'address', 'town', 'postcode', '01386 xxxxxx', '07973 xxxxxx', 'na', 'test', updateCustomerResults);
