Issue converting a Dynamic XFA PDF to Static XFA PDF when it includes text fields that span more than one page using Java

I believe I have found the solution to this issue.

I needed to render the PDF with setGenerateServerAppearance(true), and then send the output directly into Assembler to convert it to a Static XFA, with Tagging renderAtClient set False, and Tagging enabled without re-opening the document.

This generates the proper flowed content and split text fields render as expected without scrollbars or plus signs.

Here is the DDX for Asssembler:

<DDX xmlns="http://ns.adobe.com/DDX/1.0/">

    <PDF result="flattenedform.pdf" save="Full">

        <PDF source="docsource"><NoXFA flatten="true"/></PDF>

    </PDF>

    <XFAConversionSettings renderAtClient="false" tagged="true"/>

</DDX>

Here is some code I put together in Workbench/ExecuteScript that does what I needed: (not the cleanest)

Thanks Again for your interest and assistance.
