hi Arndt,
Sorry I was not very clear, I meant was:
1. I tell cayenne in the modeller to update the reverse, when editing the
relation ToB, which fills in the reverse relationsship ToA in the Reverse
Relationsship field.
2. Or I do not check the checkmark in the Relationship Info Editor Dialog,
which will leave the Reverse Relationsship field empty
In case 2 I am allowed to configure delete rule Nullify, since there is no
mandatory reverse relationsship
In case one I want to configure No Action as delete rule since Nullify is
not allowed due to the mandatory reverse relationsship. But then I get a
runtime error unkown delete rule 0 (with cayenne 1b1). It works with
beta3, but with beta3 we have problems in other places of the application
as a posted a few days ago :-((
2. One with reverse
1.
Lets say I have a 1:1 rel. ... without reverse
relationship and second relation ToA from B to A. if i I call
instanceofA.setToB(instanceofB)
and then try to access instanceofA via B (instanceofB.getToA()) will it
return null?
I suppose that without reverse relationsship I do have to explicit call
instanceofB.setToA(instanceofB) that instanceofB.getToA() will actually
return me instanceofB is that correct?
