Your hash code computation and equality comparison are both based on stuck - but that can change over time. If you mutate an object after adding it as a key within a hash map, in such a way that the hash code changes, then the key will... more 4/20/2014 12:14:47 PM

You're repeated sending the same object via serialization - and ObjectOutputStream notices that, and instead resolves this to references to the same object. If you want to effectively send a separate object on each call, add this to your... more 4/19/2014 7:22:19 PM

Look carefully at your constructor: public MyModelApp(object parent) : base(parent) { IStuffs _stuffs = new MyStuffs(this); } You're declaring a local variable called _stuffs and giving it a value. That is not the same as the... more 4/19/2014 7:09:24 PM
