assuming your orderMedia cfc function expects/accepts an
argument named
arrOrder of type Array:
<cfinvoke component="cfc.media" method="orderMedia"
arrOrder="#ListToArray(orderedMedia)#">
or
<cfinvoke component="cfc.media" method="orderMedia">
<cfinvokeargument name="arrOrder"
value="#ListToArray(orderedMedia)#">
</cfinvoke>
or, if you want to use ArgumentCollection attribute, then you
need to
first create a structure and populate it with member(s) and
then pass it
to this argument:
<cfset args = structnew()>
<cfset args.arrOrder = ListToArray(orderedMedia)>
<cfinvoke component="cfc.media" method="orderMedia"
argumentcollection="#args#">
