here is my problem :
I want to dynamically populate a listbox userd in an analytic app using values stored in a file.
the problem is that it works only after having run the app
to reproduce : load and save the app and the txt file
run it as as analytic app -> it shows all the rows of the file
modify the file by adding or removing a row
run the app as an analytic app -> it shows the same values as before
so, the question is : how shouls I design the app so that it takes the values of the file ?
