ArrayIndexOutOfBoundsException at 1:N relationship

[gb...@catsoft.de]

Hi,

I have a problem with a java.lang.ArrayIndexOutOfBoundsException: 1

I have the following:

class A
{ 
Integer pkA
};

class B
{
Integer pkA // is PK
Integer pkB // is PK too
Integer otherField;
};

B has 2 primary key fields and A only one.
So the first field pkA of Class (and table ) B is the primary key of 
Class (and table) A.
>From point of view of  A it is a 1:N relationship. I have a repository
with a collection descriptor at
A and a reference descriptor at B and both are working when I turn on
autoload.
I would like to query A and get all A where B.otherField=SomeValue.
This produces the ArrayIndexOutOfBoundsException. Can the problem be that
B has no own
pk field so that B.pkA is part of the primary key of the table B and part
of a reference descriptor
(and part of the collection descriptor of A) ?

best regards,

Guido

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
