Sort-of Yes.
We never really "persist" what is selected to any layer beyond the form because we're
only gathering attributes that which are provided to our "search" action once all the
selectable attributes.
So from a technical use-case perspective I understand that:
1. Form session scoped for simplicity with collection of record_ids (initially empty)
2. Go to database to get records (!-10) since page requested is initially 1
3. Skip preselection step since record_ids collection.size() == 0
4. Render Form
5. User selects items 1 and 3 and submits form via next page link
6. Since record_ids collection size() == 0, populate collection with selections 1 and
3.
7. Go to database to get records (11-20) since page requested is 2
8. Loop through collection to preselect -- again nothing done here
9. Render Form
10. User selects 15 and submits via next page link.
Here is where I get tripped up because in this case I would just need to add 15 to the
selection array in my form, but technically it is possible then that once they view
results 21-30, hit prev page I should show 15 as selected. If they unselect 15 and
either dont select anything or select another record, how do I track this?
Maybe I'm creating my form incorrectly using the wrong type of tag to manage my
selection list/boxes. Sorry, just been up too long without sleep and this is probably
something very trivial that I'm overlooking.
Thanks in advance!

You might want to re-present the problem. When I read your email, it seemed like
you were describing a typical use-case:
1. Get data from a persistent store
2. Populate form. If attribute indicates "selected", preselect checkbox
3. Render form (allowing user to edit)
4. Persist edits.
