@zentol hi. You are right.I want to change
"(this.state == null ? that.state == null : (that.state != null &&
this.state.equals(that.state)))" to
"(this.state == null ? that.state == null :
this.state.equals(that.state))", because equals() will check null of
that.state and if that.state is null it will return false.
What is your suggestion? Thanks.
