Hi there. I have a mapping scenario very much like the "Nested Structure Definitions" in https://jna.dev.java.net/javadoc/overview-summary.html , where I have a pointer to a structure within my containing structure, and in which I used the ByReference tag to mark the nested structure as a reference.

The problem I have, is that in JNA native function call, when the containing structure is marshalled, only the containing structure is serialized, and not the nested structure (its native memory block remains uninitialized, with zeros). I ran it throught the debugger with JNA's source code, and the write() method of the nested structure is never called. Is this normal behavior? Do I have to manually call the write() method of the nested structures?
