[jira] Created: (CAY-1538) superclass generation with inheritance

superclass generation with inheritance
--------------------------------------

                 Key: CAY-1538
                 URL: https://issues.apache.org/jira/browse/CAY-1538
             Project: Cayenne
          Issue Type: Bug
            Reporter: Marcin Skladaniec
            Priority: Minor


preconditions: cayenne model with inherited object entities.
suspected bug: the resulting generated classes are duplicating property keys, getters and setters

For example defining entity Apple inheriting from entity Fruit will generate following set of classes:

Apple extends _Apple extends Fruit extends _Fruit

The _Fruit.java defines all property keys, getters and setters for the attributes and relationships, also the PK column. _Apple.java does not have to re-define those, yet it only skips attributes, and keeps re-defining relationships and PK. (please see the pseudocode example below)

not sure if that is intended or not.


_Fruit.java
//attributes
    public static final String KIND_PROPERTY = "kind";
    public static final String WEIGHT_PROPERTY = "weight"
//relationships
    public static final String SUPPLIER_PROPERTY = "supplier";

//PK
    public static final String ID_PK_COLUMN = "id";

//attribute getters/setters
getKind()
setKind()
getWeight()
setWeight()
//relationship getters/setters
getSupplier()
setSupplier()


_Apple.java
//attributes
skipped...
//relationships
    public static final String SUPPLIER_PROPERTY = "supplier";

//PK
    public static final String ID_PK_COLUMN = "id";

//attribute getters/setters
skipped...
//relationship getters/setters
getSupplier()
setSupplier()

[jira] Commented: (CAY-1538) superclass generation with inheritance

Marcin Skladaniec commented on CAY-1538:
----------------------------------------

workaround for this issue is to define the relationships on the inheriting class level, not the base entity.
