I am using Indesign CS6 to develop fillable, accessible PDF forms. I create the fields, drag them to the Articles panel and check the that the field order is correct. I have checked "Use for reading order in Tagged PDF" in the articles panel. I then export the file to PDF, choosing the "Adobe PDF (Interactive)" format. In the export dialog box I have "Create Tagged PDF" and "Use Structure for Tab Order" checked.
When I open the file in Acrobat I first tab through the document to test if the fields are selected in the correct order. No problem. I then open up the Order Panel to make sure the reading order is correct. It is way off (1, 2, 21-32, 4-20). The document fails the accessibilty check. The suggested fix is to manually reorder fields in the Acrobat Order Panel.
More often than not, if you try to reorder an item in the Order Panel, dragging it to a new location in the list, the item disapears from the list and is completely removed from the form. You then need to start from scratch, exporting the PDF file again.
Can you build a form in InDesign that does not require manual reordering in Acrobat?
