Persistence By reachability issue Application Identity

Question

When I Persist the base object it tries to create the related objects
ParamRuleCondition has Collection of ParamRuleConditionExp and
ParamRuleConditionExp has Collection of ParametricExpValue
ParamRuleConditionExp has composite Primary Key with two keys
(ParamRuleCondition , ParametricFeature)
ParametricExpValue has composite Primary Key with three keys one of them
(ExpValue) is a String (ParamRuleCondition , ParametricFeature , ExpValue)
On saving ParamRuleCondition,
it create ParamRuleCondition and ParamRuelConditionExp properly
but tries to insert null in ParametricExpValue
The error is listed at the end
To define composite primary key for ParamRuleConditionExp
I have two extra attribute 'Id' and 'paramFeatureId'
Is this the right way of doing it?
The Pk were generated using the
com.solarmetric.kodo.enhance.ApplicationIdTool class
Thanks for your Help

I have the following object hirearchy
Class RuleCondition {
private Long Id
Class ParamRuleCondition extends RuleCondition {
private Collection paramRuleConditionExps;
class ParamRuleConditionExp {
private ParamRuleCondition paramRuleCondition;
private Long id;
private ParametricFeature parametricFeature;
private Long paramFeatureId;
private Collection expressionValues;
Class ParametricFeature {
private Long paramFeatureId;
private String parametricFeatureCode;
Class ParametricExpValue {
private String expValue;
private ParamRuleConditionExp paramRuleCondExp;
private Long id;
private Long paramFeatureId;

Answer 1

It sounds like your "PARAMETRIC_EXP_VALUE" table's "RULE_COND_ID" field
does not allow nulls. Did you create this table? If so, did you
explicitely disallow nulls from being inserted into the table?Yes nulls are disallowed for column "RULE_COND_ID" as it is part of the
composite primary key for PARAMETRIC_EXP_VALUE table.
I don't understand what you mean here. Do you mean that you are trying
to set the ID "just before it is persisted"? How are you doing this
(e.g., in the jdoPreStore method)?It is not done in jdoPreStore method.
I call paramRuleCondition.setId(new Long(<value>))
just before calling pm.makePersistent(paramRuleCondition)

One thing I would like to add is that ParamRuleCondition's id has a 'null'
value until just before it is persisted.

Thanks for your help Stephen
I changed the business object method to set the id
But now I am getting a different error
The new error is listed below
One thing I would like to add is that ParamRuleCondition's id has a 'null'
value until just before it is persisted.
But even then the Id is propogated to ParamRuleConditionExp, from where I
would expect it to go to the ParametricExpValue. But it doesn't happen.
Is my expectation right or is there a gap in my understanding of the way
KODO works?

When attempting to do what you want to do (a persistent class column as
part of the pk), you have to set both the pk field and the relation.
i.e. yourClass.setFeatureId (feature.getId ());
yourClass.setFeature (feature);
Of course that logic can be encapsulated in your business objects.
