Hi Aditya, passing non-POD objects such as connected lists, maps, etc. as RPC arguments is not supposed to work. The reason is that a pointer with a meaning in one address space is meaningless in another address space. Please refer to the Section 8.12 of the manual [1] and particularly Section 8.12.2 for more details about the RPC mechanism.
To transfer bulk data from one component to another, you may need to manually serialize your information to a shared memory buffer, to be picked up on the receiving side. See section 3.6 for the various approaches of inter-component communication.
