Addtional note adding the autocomplete="off" to the <form element gets the expects results, but I'm sure users will complain about disabling this feature

I wonder if this is due to the fact that while the id values change, the name value of all the select elements are the same. Could that be confusing the autocomplete algorithm?

Ah, Mike you are correct.  If you change the name of the select to be unique it works as expected.   Should the autocomplete algorithm should be looking at id instead of name, at least in a table?

This is basically the same as bug 201056.

Comment 9

Oh, and giving all the selects involved different names will prevent this from happening...
