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.
Thanks,
Jason
