Subject signer information does not match signer...
Date Tue, 24 Mar 2009 15:47:52 GMT
Hello,

I am getting an error when trying to use lazy loading. The root cause 
seems to be this exception:

signer information does not match signer information of other classes in 
the same package

Does anyone have an idea how I can fix this problem or what is actually 
wrong? Below is the entire exception.

Thanks,

Jeremy
