Hello,
while working with Castor JDO, I came across the
following problem:
My database mapping file contains one top-level
element which references the other elements. All
referenced elements are declared with "depends" set to
the top-level element. Thus, they are dependent on
this element. All elements have "key-generator" set to
"MAX".
When I try to insert a set of data by calling
db.create(...) with the top-level element as parameter
and no keys initialized for any element in the
hierarchy, I get an exception from my database which
tells me "Missing non-NULL value". This occurs because
the id (foreign key) for the referenced elements have
not been initialized.
Is the Key-Generator not supposed to initialize
private keys (set by "identity") AND the respective
foreign keys?
Stefan
