OIC FTP - FTP adapter write to file - File name pattern not taking the pattern specified in the mapper

Case study: 

I want to create a dynamic file name to be written to FTP folder but the dynamic file name provided in the mapper is not used by OIC. 

The file name has been mapped in the ftp mapper but the file that is written to FTP uses the file name pattern specified in FTP adapter write file action.

Example: 

file name pattern under write file.action: demo.txt

File nane in the mapper under properies : newfilename

during run output filename came: demo.txt

But expected is : newfilename

Screenshots what we did:

FTP write adpater configure page:

File name mapped in the Mapper 

Solution steps:

We should update the file name and directory name under OutboundFTPHeaderType instead in the properties filename.
