You do need to use the $button widget, but don't need to use the $reveal
widget.
Here's a working example (tested on TiddlyWiki.com)
\define choice_actions(value)
<$action-setfield choice="$value$" />
<$action-setfield timestamp=<<now YYYY0MM0DD0hh0mm0ss0XXX>> />
\end
<$button class="tc-btn-invisible" actions=<<choice_actions>>>
<$radio field="choice" value="one"> one </$radio>
</$button>
<$button class="tc-btn-invisible" actions=<<choice_actions>>>
<$radio field="choice" value="two"> two</$radio>
</$button>
<$button class="tc-btn-invisible" actions=<<choice_actions>>>
<$radio field="choice" value="three"> three </$radio>
</$button>
choice = {{!!choice}}, timestamp = {{!!timestamp}}
The $radio widget *displays* the current choice, but the choice value (and
the timestamp) are *set* by the surrounding $button widget.
Let me know how it goes.
enjoy,
