Not listing all field names on XFA form

I am currently evaluating your product (aspose-pdf-9.1 for java) and I have been conducting various test to determine if your product will fit our needs. I have an instance of a Adobe Dynamic PDF form that contains a total of 4 fields. I would expect this block of code to return all 4 fields:


String[] fieldNames = pdfDocument.getForm().getXFA().getFieldNames();
for(String xfaf : fieldNames){
System.out.println("XFA Field: "+xfaf);
}

The expected output of this call should be:
XFA Field: form1[0].#subform[0].ItemNumber[0]
XFA Field: form1[0].#subform[0].SourceDescription[0]
XFA Field: form1[0].#subform[0].ItemNumber[1]
XFA Field: form1[0].#subform[0].SourceDescription[1]

But instead I only receive:
XFA Field: form1[0].#subform[0].ItemNumber[0]
XFA Field: form1[0].#subform[0].SourceDescription[0]

Continuing testing with this dynamic form I can successfully set the value of the two seemingly missing fields and save the resulting PDF to verify:
xfa.set_Item(“form1[0].#subform[0].ItemNumber[0]”, “123”);
xfa.set_Item(“form1[0].#subform[0].SourceDescription[0]”, “456”);
xfa.set_Item(“form1[0].#subform[0].ItemNumber[1]”, “789”);
xfa.set_Item(“form1[0].#subform[0].SourceDescription[1]”, “101112”);

The resulting PDF has the fields filled correctly as specified above. I know the fields are there, but getXFA().getFieldNames() is not listing them.

Aside, Saving this same form as a Static PDF, and using a call to:
Field[] fields = pdfDocument.getForm().getFields();
will return all 4 fields as expected.

Also, renaming the fields so they are unique solves this issue in the dynamic form as well.

Is there a way to get the field names when they are not unique within an XFA form? This seemingly would prevent users from programatically filling out a form like this without guessing. Is this just a side effect of this being an evaluation version? Thank you.
