Topic: "old" Incremental Update on an PDF with cross-reference streams (Via Email), 1 Attachments

Hi all!

I ran into a problem updating an AcroForm created for PDF-Version 1.6.

The original document is created as an hybrid-reference file, which can be opened by AR5, AR6 and AR7 (but only AR7 shows the default value of the textfield - that's strange but not the main problem).
As it is a hybrid-reference file I use the standard cross-reference table to fetch the objects and update the textfield (my parser didn't "understand" compressed streams nor cross-reference streams).

I update the file by a simple "old style" incremental update with a standard cross-reference.

But now my problem is, that AR7 didn't recognize my update and shows the old default value, but all other version (AR5, AR6) accepting the update and show the new value.

I've attached an examplefile to this post.

It's a bit strange, cause AR6 (that also can handle compressed streams and cross-reference streams) did accept the update as expected - AR7 didn't...

Any help would be great!

Thanks and best regards,
Jan
