objectTranslator.cfc throwing error at line 149

I'm a bit lost on what to do, I'm trying to make changes to a record,
and I keep getting this error.

I've un-commented the try-catch block, and seen that
arguments.pathToNode is an empty string as the error says, but other
than that don't know how to interpret the error or a fix for it. I
deleted the generated xml file, but that doesn't seem to help.

Ended up putting a try/catch around the recursion paramNode calls in objectTranslator.cfc, here's the code.  So far this is working, let me know if there is a better solution.

<cftry>
<cfset paramNode(arguments.xml, parentNodePath) />

<!--- create the node --->
<cfset node = XMLElemNew(arguments.xml, ListLast(arguments.pathToNode, "/")) />

<!--- if a value has been provided, set it. --->
<cfif Len(arguments.value)>
  <cfset node.XmlText = arguments.value />
</cfif>

<!--- get the parent Node --->
<cfset parentNode = XmlSearch(arguments.xml, parentNodePath) />
<cfset parentNode = parentNode[1] />

<!--- add the new node to its parent --->
<cfset ArrayAppend(parentNode.XmlChildren, node) />
<cfcatch type="any"></cfcatch>
</cftry>

Could you post the XML it was choking on ?
