Subject exception from merging
Date Mon, 07 Apr 2008 15:27:49 GMT

I called merge on my parent entity because it is detached.

You can see from the stacktrace that something in merge() is not happening.

$Proxy13 seems to be the name of the parent's child collection property, I can 
see from debugging.

Does anybody recognise the problem?
