You don't show your code but I'll bet you are doing something like:
<cfinvoke component="foo" method="bar"/>
<cfinvoke component="foo" method="fubar"/>
This creates a separate instance for each invoke so your CFC is being
initialized each time. In order to persist instance data between calls,
you must use the *same* instance:
<cfset foo = createObject("component","foo")/>
<cfinvoke component="#foo#" method="bar"/>
<cfinvoke component="#foo#" method="fubar"/>
Note that you do NOT need a *persistent* scope per se, just a scope that
covers all the calls you need to make - in the case above, variables scope
(the default) is fine. If you need to access that single instance across
multiple pages, then request or session scope would be more appropriate.
