Manged to execute an event ib the document docReady that write into a
textfield. When we pass the document to the input folder of our process,
the event fires and write some text in a textfield and This happens
without opening the pdf, so the event is executed in "background" at
server side. Btw, we cannot manage to call a function (in docReady) that
perform validation and fill a textfield on server side. The function
works if we open the PDF, but doesn't work if we use the process we
defined.
