How to determine initial hide/show state of form button fields?

Apr 9, 2012 10:57 AM

I have a page with five rollover buttons labeled 1,2,3,4,5.  Each button when rolled shows an image in a mutually exclusive fashion.  When I load the page in Acrobat Reader, initially the first button is highlighted and the assigned image is shown, and it works as expected.  When I load the page in a custom renderer project, all the buttons are initially highlighted.  After rolling over all the buttons once (activating the enter/exit triggers in the Additional Actions dictionary) the buttons work as expected, in a mutually exclusive fashion.


My question: how is the initial hide/show state of a form field established?  I've researched the 1.7 Reference but can't figure it out.

    Initial state is set by the value and/or the D(efault) appearance.


    Details on how to render annotations and their appearances are in ISO 32000-1:2008.
