RE : 1:1 navigable && EmptyCache bug

Hi Edson,

I apologize; I wanted to say in the collection-descriptor.

Each time I have a Foreign Key reference in the reference_descriptor I have
an inverse Foreign Key in a collection descriptor.
  
Maybe I'm wrong...I thought you all time oblige to have a collection
descriptor in such case

Is it because you don't have any Inverse_foreignkey in your reference
descriptor ?

Hi!

If using EmptyCache, and you have 1:1 navigable referenced objects, OJB goes
to infinite loop trying to load the references.
The problem appear in the following piece of XML:

  Hi Edson,

  I think with EmptyCache OJB cannot detect loops in your object
  relations, because it does not maintain object identity. I'm afraid
  you need to use some non-empty cache implementation or remove the
  back-reference that causes the loop.
