Re: ArrayIndexOutOfBoundsException at 1:N relationship

[Guido Beutler <GB...@cat-gmbh.de>]

Hi,

please forget all I wrote :)
I had a error at the definition of the pk of A. A second row was defined 
as primary key too.
I think that I ran in this problem during my tests. This maybe why the 
autoload was working
when I started. With the invalid pk definition the test case wouldn't 
succeed

best regards,

Guido
