Hello,
Simple example:
class A
{ int x; };
class B
{ int *px; };
There exists a list of B for each A, which points to x.
When now serializing B:
ar & px;
I get an compiletime error, that t is of non classtype 'int'.

This error does not refer to the class it self, but it only occurs, when serializing int* in my application.
Is this a bug? Or is this a thing serialization can't do right now? I've got a workaround, so I don't need to save the px variable, but I'd like to know if this is an error or not.
From the docs: "By default, data types designated primitive by Implementation Level class serialization trait are never tracked. If it is desired to track a shared primitive object through a pointer (e.g. a long used as a reference count), It should be wrapped in a class/struct so that it is an identifiable type. The alternative of changing the implementation level of a long would affect all longs serialized in the whole program - probably not what one would intend.

Oh, I see. I just read all the Docs to pointers, and missed Objecttracking. thanks, Jens Weller
