I have a PDF with two dropdown and both are connected somehow.
If you select any value from first dropdown then based on that a list of values will be inserted into second 

dropdown to select from.
I have checked everying, there is no javascript in both dropdown and there is also no document level javascript in the pdf file.
Can anyone tell me how this is working ?

I am attaching the PDF, Please have a look
Thanks for your help

    It's a pretty straight forward case statement.  No AF or other obvious Acrobat internal function calls. 

    It is indeed odd.

     


    It does contain "AF", actually, in these strings:

     

    "Ventilation - HAF (Units: No)", "HU-Ventilation - HAF (Units: No)",

    To solve this bug of Acrobat move the code to a function in a doc-level script and call it from there, instead of putting it directly under the field's action.

    There 's a keystroke (i.e. commit) script .  For some reason it's not being shown.  Very Odd. The Dropdown also a field property that shouldn't have been set for a combobox.  But I don't think that has any affect. 

    Whatever application built this PDF (and it's not Acrobat) did something screwy.

    Acrobat hides some scripts it considers to use "internal" code. This usually happens when they contain the string "AF" in them, but there might be other reasons, too.
