frameset vs tiles

[Chris Pat]

Hello
Still struggling with a design that needs to keep to pages separate and javascript accessible on a page, BUT that the submission of one does not force a reload of the second on upon return. I know that is a definition of an Ajax call, but that will not work here for other reasons.

I hope I can ask, rather than spend a few hours "slugging it out", will a page composed with Tiles keep both frames, or in this case tiles, separate as describe above? A frameset is the simplest, but as often doesnt work. tia.
