For what it's worth, you can get the same result and have valid HTML documents as well, by writing the code you want to run last as a function, and calling that function in the onload event handler of the BODY tag.

RE: One call for two pages?
Though I would wade in with my $.02 worth. I've written pages where I spew all of the HTML out and then at the very end (after the ) I add my JavaScript. Something like: document.form[0].field.value = 'something' This way the script won't run until after the whole page is created. You might be able to use this to create your page and then write the JavaScript to go to the parent frame, grab the values you want and then push them into the page where you want them displayed. The other option I can think of is to write your server page to generate the 2 output pages and save them disk using cfhttp. Then when you load your 2 frames have those pages cfinclude the generated pages. I know you are in a clustered environment so this may not be feasible, but just a thought.

Re: One call for two pages?
OK, then you'll have to copy the results to SESSION scope and call them from
there.
Something along the lines of:
In the first page:
Then reference it on the second page by copying to local scope.

Re: One call for two pages?
How about having the top frame submit to itself and use javascript to submit
to the bottom frame? Something like:
<!--
function submitForm() {
myForm.target="otherFrame";
myForm.action="other_action.cfm";
myForm.submit();
}
-->

In that case: let the submit process create 2 pages. First create the bottom frame and put it in a variable. Then the top frame and include some code like: htmlbody = JSStringFormat(bottomframe); top.frames[1].location='about:blank'; top.frames[1].document.write(htmlbody); This should write the htmlbody into the other frame.

The problem with that is two-fold. First, I'm in a clustered environment, so
I can't use session variables. Second, I am receiving a 15K WDDX packet
back from a Python server that I am de-serializing. So setting the packet to
a client variable isn't reasonable either. The resulting variable would be
huge and a burden on the CF server because it would inherently be retrieved
on every CF call within the application.
Also, as a rule of thumb, I always have my forms submit to themselves. This
allows me to have self-contained forms which are easy to re-use and
maintain.
Regards,
Dave.

How about having the top frame submit to itself. All processing is done
normally and in the end query is set to a session variable with a unique
name. After that you add 1 javascript function using cfhtmlhead. The
function looks something like:
function reloadBottom() {
top.frames[1].location = 'blahblah.cfm?fromcache=#uniquename#';
}
On the resulting request you just grab the query from the session scope
based on the unique name. If it is large don't forget to delete the
session variable afterwards.

No, you're making sense. That's an interesting approach. The one pitfall I see is that in order to refer to the top frame's field, I'd have to use JavaScript to get the value (parent.topFrame.fieldname.value) and then write the bottom frame out entirely in JavaScript. Outside of that, I don't see how I could get at the value via JavaScript, set it to a CF variable, and then use the resulting CF variable to write the page using standard markup.

haha, i totally screwed up that post. instant replay this is kindof a wacky situation. as far as I know there are few ways to make a "recordset", or data in general, available across frames. in this case I would use a wddx recordset. -i'd run the query in the upper frame -return it to the page as a wddx recordset to the page -onload of the upper i'd refresh the lower -onload of the lower have it look at the wddx recordset in the upper and build your page from there kinda messy. interesting problem that i've never really seen a good solution to. you CAN refer to variables in other frames from the same domain. am i making sense here or am i speaking FridayAfternoonGettingTired language here?
