tmjee commented on PDFBOX-2857:
-------------------------------
Tired to modify a pdf with xfa through
{code:borderStyle=solid}
COSStream cosout = new COSStream(new RandomAccessBuffer());
OutputStream out = cosout.createUnfilteredStream();
...
// write to out and put cosout in cosArray
PDXFA xfaout = new PDXFA(cosArray);
form.setXFA(xfaout);
doc.save(...);
{code}
The output file looses all extended features. Try stripping code down to bare
minimum as in this jira description but still get the prompt saying all
extended features are lost when opening the written pdf with xfa file.
It doesn't happen in extremely simple pdf xfa.
> Saving XFA document caused prompt saying Extended features has been disabled
