To Get Dynamic filenames while using sync get FTP Adapter?

Question

Instead of looping and getting filenames after file listing...
i am thinking to use flow N.instead of while loop after filelisting..
i am able to find, different file names in the assign activity, before the invoke activity which is assigned to Sync get adapter.
but the sync get adapter is getting same file names in all the parallel flows.
i can see it can successfully transfer one file, but fails with rest of those.
is there any possibility, to pass file names dynamically to the sync get adapter..

I want to conform you again, i want to use FLOW N instead of while..
In whileloop the logic works fine, but when it comes to FLOW N , its failing
as requested, code is fallows
<assign name="Assign_InputDetails"
xmlns="http://schemas.xmlsoap.org/ws/2003/03/business-process/">
<copy>
<from expression="bpws:getVariableData('Invoke_FileListing_OutputVariable','filelist','/ns2:filelist/ns2:file[position()=$i]/ns2:filename')"/>
<to variable="Filename"/>
</copy>
<copy>
<from expression="bpws:getVariableData('Invoke_FileListing_OutputVariable','filelist','/ns2:filelist/ns2:file[position()=$i]/ns2:directory')"/>
<to variable="InputDir"/>
</copy>
</assign>
<invoke name="Invoke_GetInovice"
inputVariable="Invoke_GetInovice_InputVariable"
outputVariable="Invoke_GetInovice_OutputVariable"
partnerLink="GetSourceFiles"
portType="ns4:SynchRead_Inovice_ptt"
operation="SynchRead_Inovice"
bpelx:invokeAsDetail="no">
<bpelx:inputProperty name="jca.ftp.FileName"
variable="Filename"/>
<bpelx:inputProperty name="jca.ftp.Directory"
variable="InputDir"/>
</invoke>
where i in [position()=$i] is index variable declared in FLOW N
