File Receiver Adapter - writes empty message although ignore flag is set

Question

Hi,
i have an file FTP receiver channel configured with content conversion. I also have set the "Empty-Message-Handling" flag to "Ignore", so empty messages with 0 kb are not written to the FTP server.
My problem is now: empty file are written to FTP server although this flag is set to "Ignore".
For example: A message with the following content arrives at my receiver adapter:
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_ArticleMaster xmlns:ns0="http://ihle.com/tyredating/core"></ns0:MT_ArticleMaster>
The resulting file has 0kb.
Does anyone have an idea why empty message are not getting ignored by this setting? Although the flag is set?
Thanks in advance,
MS

ideally the file adapter will expect a message with no content in it. so i suggest you use a simple java mapping to check if there is any content between the tags, if there is no content then write out an empty string to the outputstream else pass the same inputstream out
