[Boost-users] [serialization] serializing int*

Subject: [Boost-users] [serialization] serializing int*

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.

regards,
