BuddyPress.org

Hi,
I’ve a problem with xprofile update/delete.
When you update your xprofile field, buddypress delete the entry in your database
and insert a new entry, so the field has a new ID.
This is the same think with selectbox.
If you modify a children field, it deletes all the children from database and then
create new entries.
I’m using for a custom plugin, the id of the field to display data.
So when admin delete, my plugin doesn’t find the field.
How can I prenvent from buddypress delete, or hook before and disable this function.

Thanks in advance
Harry
