Topic: (Acro)Form Fields, PDF 1.5 and Adobe Professional 6.0...

I noticed the following in a PDF generated by Adobe Professional 6, which I think does not follow the PDF 1.5 specification. I'll be really grateful if somebody cleared this up for me...

USING Adobe Professional 6, I created a new PDF from a text file and added a text field [widget annotation] to it. I gave it a tool tip and in the 'Format Tab', chose the 'Number' category with the default options. Next I created another text field with the same name. Adobe Pro. automatically applied the settings [tool tip and the number format settings] from the first field to this field [as both the fields had the same name]. I saved the PDF, opened it in a text editor and observed the following:

- There were three form fields...two terminal fields representing the two text fields that I had created and a non terminal field, which was a parent of these terminal fields and had the properties common to both these fields in it's dictionary...
45 0 obj<>/AP<>/MK<>>>

47 0 obj<>/AP<>/DA(/Helv 0 Tf 0 g)/MK<>>>

12 0 obj<>/DA(/Helv 0 Tf 0 g)/TU(der)>>

13 0 obj<>
14 0 obj<>

As is clear from the snippet above, the two terminal fields are inherting the /AA [Aditional Actions] dictionary and the /TU string from the parent field, whereas the PDF 1.5 specification [table 8.60, page 615-616] does not mention the AA dictionary and the TU string as inheritable.

Is this an issue with the Adobe Professional or am I making some mistake in interpreting the PDF specification.

Sincere Thanks,
