Element PREVIOUSPAGE is undefined in SESSION

Hi Experts,

Our website was running fine (www.joe-cool.co.uk/EN/home/home.cfm. any page that you hit now throws an error that is :

Element PREVIOUSPAGE is undefined in SESSION

application.cfc contains this line :
       
...
       <cfparam name="Session.previousPage" default="">

...

it crashes here :
...
<cfif Session.previousPage EQ "" OR Session.previousPage EQ "#cgi.script_name#">
                        <cflocation url="#CGI.SERVER_NAME#" addtoken="no">
                  <cfelseif REFind("Element ALLPRODUCTS.PRODUCTS is undefined", arguments.exception.rootcause.message) NEQ 0>
                        <cflocation url="#CGI.SERVER_NAME#" addtoken="no">
                  <cfelse> ...

I don't see why is suddenly happening, no changes have been made to anything.

Pelase help,
Adam

I'm getting a different error:

Could not create connection to database server. Attempted reconnect 3 times. Giving up.
 
The error occurred in D:\inetpub\vhosts\joe-cool.co.uk\httpdocs\model\products_collection.cfc: line 9
Called from D:\inetpub\vhosts\joe-cool.co.uk\httpdocs\Application.cfc: line 462
Called from D:\inetpub\vhosts\joe-cool.co.uk\httpdocs\Application.cfc: line 449
Called from using password: line -1
Called from using password: line -1

7 : 	<cffunction name="init" access="public" output="yes" returntype="model.products_collection">
8 : 		<!--- retrieve products from database (jcstktabl) --->
9 : 		<cfquery name="q" datasource="joecool_web">
10 : 			select * from jcstktabl order by jcid desc
11 : 		</cfquery>

Open in new window

Regarding your session error, you should have this set in your onSessionStart function of your Application.cfc file:

<cfset session.previousPage = "">

Although the cfparam should also work, depending on where it is in relationship with your block of code that is throwing the error. If would, of course, have to be called before it. Placing the line above in the onSessionStart method would ensure the order of execution.

Hi Gdemaria,

Many thanks for your help. The database was deleted by mistake by our hosting company.

We did restart both application and server, recreated the Cfm DSN and it does work fine now.

However, I totally agree with your point of view, this website is old and will soon be replaced by a state of art website, including the arguments you mentionned.

Many thanks
Adam.

Wow, the hosting company accidently deleted your database! Glad you survived that!
