How can I make this function thread safe?

i think you should still investigate using conditional loop in your
function instead of having it call itself over and over with each
iteration, passing more and more data around... it does not look like
the best setup to me...

It's okay thanks. I figured it out. All it required was a simple:

<cfargument name="breadCrumbArray" hint="" required="no" type="array" default="#arrayNew(1)#" />

<cfset var myArray = arguments.breadCrumbArray />

All I needed to do was assign the argument to the var scope. Figured this out exactly when I post the message - typical!! Haha.

Thanks.

is your function calling itself in its execution? that's why your array
is being re-created with each call...
sounds like you should be using a conditional loop... maybe something like:

<cfset var functionItemID = arguments.itemID />
<cfset var bcArray = arraynew(1)>

<cfloop
condition="application.tags.hasParent(functionItemID,arguments.itemDeleted,arguments.itemState)
is true">
<cfset
arrayAppend(bcArray,application.tags.getItemField(functionItemID,"item_id"))
/>
<cfset functionItemID =
application.tags.getParent(functionItemID,arguments.itemDeleted,arguments.itemState)
/>
</cfloop>

<cfreturn bcArray />

[NOTE: absolutely untested]
