How did you build the radio buttons?
What export to PDF settings are you using?
As per the tutorial somewhere on this incomprehensibly complicated website. I built them in InDesign 6 with a rectangle frame tool and used the Buttons & Forms palettet to convert them to radio buttons, then exported the whole thing as an interactive PDF to Acrobat.
It doesn't seem like much of a problem until you have dozens of radio buttons, which you've converted to show borders and then realize you need to fix something in InDesign and will have to re-export the PDF again.
By default, out of InDesign CS6, radio buttons should be visible.
Below is a sample form I built from CS6 and you can see the radio buttons.
I'd suggest restoring your InDesign preferences and see if that helps.
Here are instructions for restoring preferences:
I'm having the exact same problem. Weird thing is that they were working and now they are not. I worked on them on my work computer, and then on my home computer and that's when the problem started occuring.
I restored preferences, just created a new document to text it, and it still doesn't work.
The buttons are visible if the 'highlight existing fields' or whatever is selected but not if they are not. And they don't print as visible.
They are visible in Apple Preview though.
For example, this is what it looks like without 'Highlight Existing Fields':
And this is it with 'Highlight Existing Fields':
So it does appear, but it doesn't print with the buttons enabled.
It's so weird because it did work before. I reexport forms that did work and they don't have the radio buttons show up.
Yes, I tried that but same thing happened.
It appears that if I open the PDF in Acrobat, click on the radio button and access Properties, I have to change the border color from nothing to something and it is then visible. I have no idea why it exports like this from InDesign or how I can fix it, but at least I have a solution, though it is an awkward one.
I'm also experiencing this problem. If 'Highlight Existing Fields' is off in Acrobat, I can't see the outline of the radio buttons. The above Acrobat>Radio Button>Properties workaround renders them visible, but the form I'm working on has around 30+ buttons, making it a very time consuming 'solution'.
Is this a bug, or simply how the form fields work in InDesign CS6? After waiting so long for form field creation tools in InDesign, it would be very frustrating if we still have to go in and change individual properties in Acrobat every time we want a form to work/look correct.
Yeah, that's exactly what I have to do. At least you can shift-select elements so you can change all properties at once. But yeah, big pain.
