If I'm using the gantt chart, delete some values in the grid (used as functions parameters) and don't refresh :
even if fields are empty in the grid, functions using them as parameters seem to pick up the values that I just deleted, as if the gantt kept them in memory. (Note that the gantt looks empty... So the fact that it keeps the values in memory is not apparent.
If I do a refresh before doing other stuff, it's okay.
Pierre : Are you aware of that ? If you are , I won't develop further. Otherwise, I can try to find the specific steps to reproduce it.
