Radiobuttons again...

Radiobuttons again...

[Henning Hraban Ramm via ntg-context]

Hi Hans,

I know you hate form widgets, but I found a clue what might be wrong 
with radiobuttons.

While we can’t fix the behaviour of viewers, ConTeXt’s radiobuttons 
misbehave if they don’t have a custom symbol (that OTOH is not shown in 
many viewers).

If I don’t use a custom symbol in \definesubfield, all subfields are 
activated together, which is clearly wrong.

I hope that’s an easy fix.

Hraban

\definesubfield[CGPerson][][] % doesn’t work

\definesubfield[CGPersonA][][x,-] % works, but ugly
\definesubfield[CGCompanyA][][x,-]

I’d like to join CG as a \field[CGPerson]\ person / \field[CGCompany]\
