Hi Alexander,
>From the description you give, and the code you show, I don't see any
reason why things would go wrong.
However, I think it might be useful that you also show your transition
function. You are using references very intensively, even in places
where they are not necessary, and I'm wondering if this could have
lead to a bug in your transition function -- something like a bad
state left after the first execution of the transition, preventing the
next executions to do their job.
More specifically, in the script above, radio does not need to be a
ref. The successive instantiations of the radio reference could be
inlined into simple definitions (radio = this ; radio = that(radio) ;
etc) to the same effect. The only uses of !radio I see are executed at
initialization time: the content of the reference cell is retrieved at
that time, after which it is not looked up anymore, so any change of
the contents of the reference would be useless -- I don't see any such
instantiation in your code, so there's no real problem so far.
Hope this helps,
David
