Incorrect highlighting

[apuchitnis]

For the file:

package improbable;

// The enumeration
type ActivityData {
  enum Activity {
    SITTING = 0;
    STANDING = 1;
    WALKING = 2;
    RUNNING = 3;
  }
}

type ActivityChangedEvent {
  ActivityData.Activity new_activity = 1;
}

// Parameters for transitioning between activites
component ActivityState {
  option queryable = false;

  id = 1007;
  // these should not be updated directly. Use the changeActivity event!
  ActivityData.Activity current = 1;
  ActivityData.Activity previous = 2;
  // The main event to change state via
  event ActivityChangedEvent change_activity;
}

The plugin incorrectly reports "Expected ";" or "=" after event ActivityChangedEvent" and highlights "change_activity" with a red underline.
