Check if interactive form exists in ColdFusion before using cfpdfform action=“read”

Question

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

To read the form values I use the command:

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

But if a PDF without a form is uploaded (ie 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>
