collection-descriptor should have option to define which key is to be used when
creating collection
---------------------------------------------------------------------------------------------------
Key: OJB-69
URL: http://issues.apache.org/jira/browse/OJB-69
Project: OJB
Type: Improvement
Components: PB-API
Environment: ojb 1.0.1
Reporter: Joose Vettenranta
if class has 2 primary keys or index keys / id fields, then it is not possible
to define to collections which id field to be used.
Like if I have 2 id's running, one is unique for that class and another one is
unique to all classes, say like this:
A.class { id, gid }
B.class { id, gid }
C.class {id, gid}
could be like: A {1,1}, A{ 2,2}, B{1,3}, A{3,4}, B{2,5}, C{1,6} ...
in repository.xml
<collection-descriptor name="childrens"
element-class-ref="net.vettenranta.Children">
<inverse-foreignkey field-ref="parent_id"/>
<!--- proposed tag -->
<foreignkey field-ref="id" />
</collection-descriptor>
<collection-descriptor name="globalChilds"
element-class-ref="net.vettenranta.GlobalChildren">
<inverse-foreignkey field-ref="global_id"/>
<!--- proposed tag -->
<foreignkey field-ref="global_id" />
</collection-descriptor>
