How do I keep from getting the Form data expired, please reload message?

Clustered servers?  Are they sharing session scope?

Can you post the code of the receving page.  You may just need to some extra form handling on the 2nd page.

I am using CFMX7 Std Ed, so I am not clustered. Although they are behind a load balancer.  The servers are sharing session data via CFID:CFTOKEN and storing session data in db.  That is working beautifully.  Here is the content of one of the pages in question:

<cfform wmode="transparent" timeout="600" width="#pagewidth#" format="flash" height="415"  skin="haloblue" style="background-color:##D4DADF;color:##274460;margin-top:0;margin-bottom:0" target="RegistrationFrame"   action="#actionpage#" method="POST" onload="#hideLoader#" name="Seller_Reg" preloader="false">

Where are the values in the cfinput coming from ( a query, form, session) I can't tell.  There is no scope.

Query

What is the value of the variable that you are putting into the onLoad attribute of the CFFORM

OnLoad calls a function, hideLoader, to hide a Loading, Loading, Loading graphic.

Let me mention, that we just moved to a multi server config and this did not happen when we were just on a single webserver, so I am 99.9876% sure it has something to do with jumping from one server to the other between pages.  I do not believe that my load balancer is set to sticky session however...

sorry for the endless questions but when the server tries to load this page you get the error?  or is it on the submission of this page?

and:

<cfinput name="button" onClick='#checkFieldSet("address,city,state,Postal_code,phone","Seller_Reg",submitReg)#' onKeyUp='#checkFieldSet("address,city,state,Postal_Code,phone","Seller_Reg",submitReg)#'  type="button" style="width:135;" value="#submittext#" tabindex="190">

In this code segment why are is the whole JS here in #'s ?

The error is sparatic at best, but happens when the page is loaded not when it is submitted.  The js code here validated that data and required fields before allowing the user to move to the next accordian and or tab in the form.  No worries on the endless questions, if you can help me solve this, I will answer and answer and answer...

I've looked and looked and I don't see anything that jumps out at me that would be causing this.

Here is a link to the page live.  Maybe if you see it, it will trigger something...

Thanks for your efforts anyway, I really do appreciate it.

I went to the link and after refreshing a few times I see the error, then it would not go away.

Are you clearing the form each time, or doing some sort of purging to ensure a clean load each time?

Yep. I am using this code:

<cfheader name="Cache-Control" value="no-cache">
<cfheader name="Pragma" value="no-cache">

I would for for kicks try putting a cfflush after those cfheaders.

Hey, at this point I will stand on my head and cross my lips if that would help.. I will let you know.

No luck.. Same results.

Ok... I did some testing.  I run firefox with flashblock and when I don't let the loading movie play I don't get the error.  Try removing it completely and then test it.  It may have to do with the rendering time of the 2 falsh objects.

We tried this and to no avail.  We also, just created a simple flash form with 1 input field, all static, nothing dynamic at all.  Played with turning on and off the preloader with nothing else but a simple flash form and we are still getting the message.  

Well....I'm out of ideas.  Sorry I was not able to assist.  Good luck.

I have opened a case with Adobe.  Thanks for your help, I greatly appreciate it.

Anytime.  Glad you figured it out.
