<cfchart> image expired when printing

[ksynergy]

I have an application that makes use of the <cfchart> tag to produce graphs
from database records dynamically. The graphs all appear normally on the web
pages, but on some computers the graph will be replaced by an 'image expired'
message when printing the page. I have seen a lot of discussion of 'image
expired' issues with <cfchart>, but none of them indicate that it is related to
client differences.

The server I use has had the 'patch' applied for correcting the general
problem with expired images, but it doesn't seem to work for all users. While
it seems unlikely, is there a setting in a client browser that could account
for the fact that the printed page would appear different for different users?
I have two computers with different operating systems (XP and 2000), but the
same browser (IE 6.0) that fail to print the graph ('image expire'). Another
computer running XP produces the printed graph.

This has me baffled. Does anyone have any suggestions?

Ok there's a lot going on with cfchart in the way of patches and fixes.

First, what version of CF are you using?

Please verify that you have these hot fixes:

in the user comments. The CF7 recipe requires adding or changing one line.

Thanks for the links. I have forwarded them to the support person at the
location providing my CF hosting. I believe he has already made some of the
changes, but I don't know the details of what he has or has not done so far. If
I hear back that all of them have already been made, I guess I'll be back
looking for other ideas.

I find it very strange that the problem would be limited to a couple of
computers and not appear at all on others. I tried a home computer last night
and it displayed the graph for printing with no problem. A laptop using the
same connection failed to show the graph when printing.

The problem is semi-random, so some of the variation is coincidence.
Also, browsers handle caching and printing differently -- and IE also behaves
differently from one windows version to the next.

Finally, check those links yourself.
Many of the suggestions are applied at the program level (you), not at the
server level.

You can change the timeout settings for your cfchart call.
More effectively, you can bypass the graphData.cfm. This has to be done by
changing your code.

Good luck,
