The problem with the second example is basically that variable substutions
like $(old)$ are applied before the macro is executed. That means that the
value of the variable "old" that gets substituted is the one that was in
force at the point that the macro was invoked. By the time your <$set>
widget is executed the macro content will have already been substituted.
The solution is to use an inner macro:
\define inner()
<$button set="$(storyTiddler)$!!done" setTo=<<addThis>> > text </$button>
[[$(old)$]]
\end
\define outer()
<$set name="old" value="test">
<<inner>>
</$set>
\end
Hope that helps,
Best wishes
