I found this article on counting documents and gave it a try. My process reads a flat file with 3 rows, executes a split documents into 3, counts in a Data Process component, merges them back to one and then generate a message with the count. I have set the DOC_COUNT into my process properties object as a string but question as to how the code knows which process properties to populate? At any rate, I do not get a value set in DOC_COUNT. Is it possible that this code is older than the current version supports?
