title: Unsupported concurrent change during composition
body: <p>Anyone please advise what I can do this.  I do have a state variable that is updated in the composition and elsewhere.  Do I need a lock to ensure that it is not changed at the same time?</p>

      java.lang.IllegalStateException: Unsupported concurrent change during composition. A state object was modified by composition as well as being modified outside composition.
