Hi Robert, Thanks for your suggestion - I's actually doing all the export in different header file (I mentioned previously in another posting) containing all the export to reduce compile time. But moving the export in ConcreteCondition.h and CompositeCondition.h causes the crash to turn into a "unregistered" exception. Now, I guess I can work on it. If it doesn't work, I'll get back to the same posting. Regards, ~ Soumen On Tue, Sep 22, 2009 at 10:36 PM, Robert Ramey <ramey@rrsd.com> wrote:
Try adding
BOOST_CLASS_EXPORT(ConcreteCondition)

Hi,
I've following class hierarchy:
FilterCondition <---+--- CompositeCondition | +--- ConcreteCondition
FilterCondition is ABC. FilterCondition has certain data members which I need to serialize.
I already have another class "Table" for which serialization works perfectly. Now, I've added a pointer of type "FilterCondition" as a member to "Table". Say, the member name is "filterCond_".
Now, as soon as I add following line in Table::serialize(), I get a crash :
ar & filterCond_;
This happens even though I make body of FilterCondition::serialize(), CompositeCondition::serialize() and ConcreteCondition::serialize() empty.
In Table::serialize(), I've verified that filterCond_ is a valid pointer. I've declared FilterCondition as abstract through BOOST_CLASS_ABSTRACT macro as well.
