Client Variables Problem

[Amosl]

I'm not sure where to post this so I'll start here.


We have two codlfusion servers, one is running coldfusion 5 and the other is running coldfusion MX version7.
We are sharing a sql database between the server to store client variables so that when someone logs into one they are logged into the other. In the process of debugging a problem, I noticed a few weird things. On the MX server if I create a page to dump the client structure, there's no problem, however, on Coldfusion 5 when I run the code <cfdump var="#client#"> I get the error:

Error resolving parameter CLIENT


If I output the member id <cfoutput>#client.cfid#</cfouput> it shows the appropriate information, why doesn't it recognize the client structure in the cfdump?

Moreover, I've created my own client variables like client.memberid . When I run #GetClientVariablesList()# it shows client.memberid as existing, but when I try to output its value with <cfoutput>#client.memberid #</cfouput> I get the error:

Error resolving parameter CLIENT.MEMBERID



Any idea why coldfusion 5 isn't reocgnizing the structure and the custom variables?

It's obviously a known CF5 limitation.

Have a look at http://www.cflib.org/udf.cfm?ID=142 - this will likely solve your problem.

Hope I got you right, and this will help.

Thanks! I'll take a look

I just took a look and am not sure this is going to solve the problem. The problem seems to be that when the coldfusion MX server updates or creates the client variables in the database, Coldfusion 5 can't recognize them. When Coldfusion 5 updates or creates a new variable, Coldfusion MX recognizes them with no problem. Do you by any chance have a link that mentions the limitations of CF 5?

[Fernis]

What kind of content do you have as client variable values?

I know for a fact that CF5 can't have structures or arrays stored in client variables. Probably unrelated to your problem anyway, but I just thought I'd mention.

Are you using exactly the same CFML code in CF5 and CFMX to both read and write the variables to/from DB?

ColdFusion 5 doesn't recognize CFMX client variables because the format is slightly different between CFMX6/7/8 and CF5.

I would recommend *not* sharing client variables between CF5 and CFMX.
