[XForms] Question #2: Relying on menu subitem IDs after fl_delete_menu_item().

[Jason Cipriani]

To subscribers of the xforms list

Let's say I have a menu with these items, created in fdesign:

1. Red
2. Green
3. Blue

So the IDs (returned by fl_get_menu) are 1, 2, and 3.

If I use fl_delete_menu_item() to remove the second item (id = 2),
then I've observed that the IDs of the other menu items do NOT change,
leaving the menu like this:

1. Red
3. Blue

This is convenient and is what I want to happen, I was pleasantly
surprised when I noticed it. However, I was always under the (possibly
incorrect) impression that menu item IDs *always* corresponded to the
index of the item (so Blue would have been changed to 2 rather than
remaining as 3).

Is this ("Blue" keeping it's ID of 3) a bug that coincidently worked
out well for me? Or is this intentional behavior that I can rely on in
the future?

Thanks,
Jason
