That's the way the proxy classes are  functioning (caching). But in new Native API for IRIS there are no proxies, just class methods/functions are called from app and I think, it should be pretty the same as calling this methods/functions from terminal window.

Hi.

As I've mentioned in previous post I'm using workaround, but I think it's a bug in API, because the same method works fine in terminal window without explicite set the objects to null (all used objects are released and consequently all locks are released also - expected behaviour in class with procedure block enabled).

I'm setting all referenced instances to null in COS to release locks as workaround. But I'm not sure it is a bug or expected behaviour...
