I am working on a tool that will allow users to rename form fields by pulling
the current form fields out of the PDF and then displaying an HTML form
containing the old name and a text input for the new name. When the form is
submitted, I loop through the form fields and rename each form field that
has a new name.
This is working fine if the existing field name is a number and I change it
to another number but it fails if the field name contains text. For
example, "1" would easliy be renamed to "11" but "field1" cannot be renamed
to "field11". The fact that the field name contains text is causing the
renameField method to return false.
If anyone has any ideas on what to try, I would appreciate it. Here is the
code I'm using:
<cfset pdfReader = createObject("java", "com.lowagie.text.pdf.PdfReader") />
<cfset outputStream = createObject("java", "java.io.FileOutputStream") />
<cfset pdfStamper = createObject("java", "com.lowagie.text.pdf.PdfStamper")
/>
<cfset pdfWriter = createObject("java", "com.lowagie.text.pdf.PdfWriter") />
<cfset pdfReader.init(fullPathToInputFile) />
<cfset outputStream.init(fullPathToOutputFile) />
<cfset pdfStamper.init(pdfReader, outputStream) />
<cfset thisForm = pdfStamper.getAcroFields() />
<cfset strFormFields = thisForm.getFields() />
<cfset original_field = JavaCast("string", arguments.oldFieldName) />
<cfset new_field = JavaCast("string", arguments.newFieldName) />
<cfif original_field neq new_field>
<cfset renameresult = thisForm.renameField(original_field, temp_field)
/>
<cfset renameresult = thisForm.renameField(temp_field, new_field) />
</cfif>
<cfset pdfStamper.close() />
<cfset outputStream.close() />
THANK YOU!
