For the first one, you're making a query string that has lines like
foo = rec.bar
where you really want
foo = <value of rec.bar>
So for execute you want something like
'' ... foo = '' || rec.bar || '' ... ''
(possibly requiring casts)

As Tom said, this looks like something else. Do you have a rule on
currentlist that also does an update on currentlist, perhaps forcing
certain values or something?
