QuickForm bug and patch, on removeElement()

QuickForm has a bug in the removeElement. When I remove an element which is not at the end, then the elementIndex is updated, but not renumbered, so when i add another element at the end, addElement() obviously uses count or sizeof to determine the the index of this new element Example: remove user[password1] the index before removing: Array (

    [action_save] => 0
    [action_cancel] => 1
    [user[email]] => 2
    [user[name]] => 3
    [user[password1]] => 4
    [user[password]] => 5
    [user[id]] => 6

) the index AFTER removing: Array (

    [action_save] => 0
    [action_cancel] => 1
    [user[email]] => 2
    [user[name]] => 3
    [user[password]] => 5
    [user[id]] => 6

) here i add an element (with the same name - which is not important) remove user[password] the index before removing: Array (

    [action_save] => 0
    [action_cancel] => 1
    [user[email]] => 2
    [user[name]] => 3
    [user[password]] => 5
    [user[id]] => 6
    [user[password1]] => 6

) the index AFTER removing: Array (

    [action_save] => 0
    [action_cancel] => 1
    [user[email]] => 2
    [user[name]] => 3
    [user[id]] => 6
    [user[password1]] => 6

) this patch solves it, at least for me. it might not be the coolest code to do that, but i guess you QuickForm guys have a better solution at hand within seconds RCS file: /repository/pear/HTML_QuickForm/QuickForm.php,v retrieving revision 1.108 diff -u -r1.108 QuickForm.php
