ftp from chapter 3

i am having a little trouble with your ftp example from chapter 3

when the inbound ftp server downloads the files to the 'out' directory it names them like:

2e202df7-c798-11dd-9fb1-9fa3568dc229.dat
2e20a332-c798-11dd-9fb1-9fa3568dc229.dat
2e20ca49-c798-11dd-9fb1-9fa3568dc229.dat
2e20f15c-c798-11dd-9fb1-9fa3568dc229.dat

the actual file names on the ftp server are:

mpw.dat
postgres.txt
references.txt
rsync.txt

question: why are the file name in the 'out' directory so different then the actual
file name? i would expect that the names downloading would be the same?

polling does not work the 2rd time. i would expect that it should poll with
the frequency declared in the config file; instead the 2rd time through i get an
exception?! is there an 'outputPattern for the ftp connector as i would like to put
a time stamp on the downloaded files.

here is my config file

ok this takes care of the file name problem:
now i can save the original file name plus add a date stamp to it.
the polling problem still exists. the first time the Poll Frequency works the 2rd time
i get:

INFO 2008-12-11 17:34:50,596 [connector.ftp.0.receiver.6] org.mule.DefaultExceptionStrategy: There is no current event available, routing Null message with the exception

Hey Michael,

I think this might be related to the following JIRA issue:

http://mule.mulesource.org/jira/browse/MULE-3192

Can you confirm the stack trace is the same or paste it here?

Thanks,
-jd

Michael,

This seems like the same issue in the JIRA - I'll add a note advising as such to CH3.

Thanks,

This should be fixed in the upcoming Mule 2.1.3 and Mule 2.2 releases.
