A client's web hosting company recently moved the website to a new server
(running CF10). One function of the website is to take information submitted
by users and use that data to populate PDF forms and then save them to disk.
That process is now resulting in the following error message:
An error occurred while reading source for the cfpdf tag. Error: Variables
written as a file by specifying destination in a tag cannot be used again.
The code that is listed as the culprit is the last line of the following:
<!--- Fill PDF form --->
<cfpdfform action="populate" source="#variables.SourcePDF#"
name="pdfFile">
<cfpdfformparam name="fieldName" value="fieldValue">
<!--- more of the above --->
</cfpdfform>
<!--- Flatten PDF --->
<cfpdf action="write" source="pdfFile"
destination="#variables.DestinationFile#" flatten="yes" overwrite="yes">
This block of code is followed by several others that are just like it except
that the variables.SourcePDF and variables.DestinationFile variables have
different values in each. Thinking that, maybe, the problem was that the
pdfFile variable was being used again (although being reset with new content at
the start of each such block) in subsequent blocks, I added some code to
explicitly reset the value of pdfFile after each write/flatten. I can't
replace the variable with a new one (e.g., pdfFile2) since some of those blocks
are in loops that iterate different amounts of times based on circumstances.
I've never seen this error before, certainly not while the website was on the
previous server. Any ideas?
Thanks in advance.
