RE: Frames and variable scoping
Thanks for the help. I am coming into an application that is already deployed. I'm here to fix bugs and add functionality. I am in the process of converting a lot of stuff to a few session scoped structures. The scoping going on in the frameset and frames is a little funky. My first goal is to get all of the variables passed and scoped properly. And if I had thought about how the thing was working, I would have been able to answer my question. Doh! The form thing is very slick, though.

Your only option here is to generate the frame tags on the fly using CF and put the form variables in the url string for the SRC attribute.

You could also store the variables in a persistant scope, but it's probably not the best idea. If you do decide to do this there is one very easy way to do it: cfset session.theForm = form (this works because form is actually a struct pointer which is getting copied into the session.theForm variable) then you can access the variables later like this #session.theForm.fieldName# ~~ Get the mailserver that powers this list at http://www.coolfusion.com FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Archives: http://www.mail-archive.com/cf-talk@houseoffusion.com/ Unsubscribe: http://www.houseoffusion.com/index.cfm?sidebar=lists

Steve went through something like this although using a hidden frame but it's still passing variables through a frame.
