I found during excercise of having two separeted EAR that I have to swithc the CallByValue to 'true' in order to have ears work I'm a little bit lost with this 'CallByValue'. My question is what exactly CallByValue does and when. 1. When using local interfaces: - passing is always by reference, and CallByValue has no impact? - or CallByValue setting has impact also on local interfaces? 2. When using remote interfaces, when 'CallByValue' must be set to true?
