Set Listbox Selection Name To form_name_selection_name
If the form contains a listbox, the corresponding selection
should be named as follows : form_name_selection_name (form_name is the id of
the form in lowercase).
The selection_name is used to find in a dictionary the parameters
used inside a listbox. Generally we want a different selection_name for each
listbox. In some cases, you could set the selection_name to another value.
