[odb-users] collection mapping error

[c.sell at byterefinery.de]

Hello Boris,

I have been able to boil down the error to what I consider the  
simplest form. It requires the collection to hold QImage and therefore  
depends on my custom profile. However, I seriously doubt that the  
traits code itself is the problem, as almost none of it ever gets  
executed.

The test program simply tries to persist one object which holds a  
vector<QImage>. The image itself is invalid, and therefore gets  
translated to a NULL marker. There is no data copying etc. performed.

However, the very first insert leads to said object_already_persisten  
error. if anything, this error is in error.

regards,
Christian
