When you use the $(variable)$ construction inside a macro, it substitutes 
the text literally, without rendering.

So when the #*#@&* DO things render? And how do you control it? This is the 
kind of thing that can make you bang your head against the wall for hours.

Fortunately, we now have the <$wikify> widget. The <$wikify> widget renders 
the text it is given, allowing a more sane programming flow. So your code 
can now be written:

\define myStateTid() """$:/state/$(currentTiddler)$"""

\define buttontest2()
<$wikify name=hawaii text=<<myStateTid>>>
  <$button set=<<hawaii>> setTo="edit">Press2</$button></$wikify>
