[Click] empty file

[Enrico]

Hi Eddie, 

this is my configuration:

a :: AggregateIPFlows

require(models);
d::FromDevice(eth0)-> Strip(14)-> CheckIPHeader(BADSRC 18.26.4.255
2.255.255.255 1.255.255.255)
-> IPClassifier(tcp)-> a -> TCPCollector(tcpinfo.xml)
-> Discard;

A lot of packets is arrived from device eth0 while my configuration was
running...then i type ctrl+z and click is stopped. 
In the click file folder there is tcpinfo.xml but is locked and empty..
ToDump and FromDump work now ... but TCPCollector no..
How can i view a xml file and how can i view TCPCollector's information?
