Check interactive form exists in coldfusion before using cfpdfform action="read"

Question

Hi there,

I'm using cfpdfform to read values from an uploaded PDF form created in Adobe Livecycle and then filled in using Adobe acrobat Acrobat.

To read the form values I use the command:

<cfpdfform source="#pathToNewPDFFile#" action="read" xmlData="xmlFields" />

But if a PDF without a form in is uploaded (i.e some other PDF) coldfusion errors with the following:

The source PDF document is not an interactive form.

Is there any way I can test for the presence of a form in a PDF in coldfusion without needing to catch and interpret this error?

I've tried cfpdf action="pdfinfo", but none of the variables appear to change between an interactive and non interactive form.

Thanks,

Tom

I'd do a simple

<cftry>
  <cfpdfform source="#pathToNewPDFFile#" action="read" xmlData="xmlFields" />
  <cfcatch>
    <cfset xmlFields = XmlNew()>
  </cfcatch>
</cftry>
