Issues dynamically setting jca.ftp.FileName dynamically from BPEL Flow in Oracle SOA Suite 11.1.1.7

Howdy,

I have a SOA composite which contains two FTP adapters.  The first FTP adapter executes a file listing operations to retrieve a list of all the files on a vendor's FTP site, and the second FTP adapter exists within a loop executing a synchronous read on each file detected within the invocation of the first FTP adapter.  When I try assigning the jca.ftp.FileName property though, it does not appear to be taking.  My jca file looks like:

  <endpoint-interaction portType="SynchRead_ptt" operation="SynchRead">

    <interaction-spec className="oracle.tip.adapter.ftp.outbound.FTPReadInteractionSpec">

      <property name="PipelineFile" value="DecryptionPipeline.xml"/>
