cdbt_crud_get_data_sql error

Hello:

I have been able to use cdbt_crud_get_data_sql filter to extract some data to the table displayed by cdbt-view. But when trying to use it with cdbt-edit, behaviour seems quite inestable. Table can be seen OK, but when trying to edit an entry from it the plugin doesn’t show the correct one, it is like it had lost the index and it doesn’t know which entry must show.
Could this behaveour be avoided?
Thanks for you great plugin!
