Woonsan Ko commented on SCXML-160:
----------------------------------
Fixed as described in the description.
Also LCA cannot necessarily be a Parallel, so added checking if it is Parallel
before casting.
Thanks a lot for reporting this with a solution!
Cheers,

> The line 90 of the
> /commons/proper/scxml/trunk/src/main/java/org/apache/commons/scxml/semantics/TransitionTargetComparator
> (compare(...) method)
> looks like this:
>
> State s = (State) iter.next();
>
> The cast to State causes a cast exception in case if the state machine has
> nested parallels (without intermediate states). The line should be replaced
> with
> TransitionTarget s = (TransitionTarget) iter.next();
