ListFile processor is not detecting all new files

[#1]

I have triggered dataflow and its running everyday. For 1st run, ListFile is able to list files and pass it on to next starge FetchFile. But when i touch file in my input directory, ListFile is unable to list those files. 

[#2 · Accepted solution]

This problem should be solved in NiFi 1.8.0.

I tested the scenario in MiNiFi 0.5.0 (based on  NiFi 1.7.0). After I executed 

find . -exec touch -m {} +

ListFile would list files again.
