If I use the remove item from list action to remove an item from the middle of a multi-value field then the delta values for the field items end up non-contiguous.

I'm not sure if this is really a bug—I can't seem to find any firm info on wether the delta values are allowed to have gaps, but it certainly causes some problems for me in views if there are.

I don't think it should create an issues. I think the field-API stream-lines the delta value in its form-code, but when saved programmatically. Probably this would be best fixed directly in core to stream-line the values before saving them. So maybe create a core-issue for it.

I have a problem when "Remove an item from a list" action is used. I have two lists, A and B filled with users from my site.

List A:
Peter
Tom

List B:
Sam

I have a flag action. When I flag the node, I have the actions to remove my username from list A and add it to the list B.

If I'm logged as Tom (the last user from list A), I get the correct behaviour (List A with Peter/List B with Sam and Tom)
BUT, If I'm logged as Peter (not the last user from list A), I get list A empty and List B with Sam and Peter)

So, only when I remove the last item from the list, it works, removing every other user gives the error above.

My lists are views references (don't know if it's usefull information...)
