What types of scripts are extracted?

Document-level JavaScript (Names > JavaScript), AcroForm field actions (calculate, validate, format, keystroke), and XFA scripts embedded in the XML template.

What causes the 'Form.root.view is null' error?

This error occurs in newer versions of Adobe Acrobat when a document-level script calls Form.init() or Form.build() at open time — the XFA view is not yet initialized at that point.

Is the PDF sent to a server?

No, all processing happens entirely in your browser. No data is transmitted.

How can I fix XFA scripts in Acrobat Pro?

Adobe Acrobat Pro does not allow editing XFA scripts directly. You need Adobe LiveCycle Designer or AEM Forms Designer to edit dynamic XFA forms.
