Hi
While generating Java code for a self many-to-many relationship depicted in the attached diagram with parameters shown in the attached screen copy the DBVA code generator fails to distinguish between the two instances of PERSON in the Person_has_lendersProcessor.java.
The two generated instances appear with the same name as shown below:
import org.orm.PersistentException;
/**
* ORM-Persistable Class
*/
public class Person_has_lendersProcessor {
...
private int personid;
public void setPersonid(int value) {
this.personid = value;
}
public int getPersonid() {
return personid;
}
private int personid;
public void setPersonid(int value) {
this.personid = value;
}
public int getPersonid() {
return personid;
....
This leads to the following compilation errors:
src/Person_has_lendersProcessor.java:49: personid is already defined in Person_has_lendersProcessor
private int personid;
^
src/Person_has_lendersProcessor.java:51: setPersonid(int) is already defined in Person_has_lendersProcessor
public void setPersonid(int value) {
src/Person_has_lendersProcessor.java:55: getPersonid() is already defined in Person_has_lendersProcessor
public int getPersonid() {
^
Advice, comments appreciated.
Best regards
Mikhail

Do you have the JSP Sample checked?
If so, could you post your Person_has_lendersProcessor.java.
Best regards
Mikhail

Note also that the SMART association should be selected.

Dear Mikhail,
If sync the ERD to Class Diagram, it should be only 1 class Person with 1 self many-to-many association, which result in generating one jsp file (PersonProcessor) only, and should not generate Person_has_lendersProcessor.java. Our project is attached.
Can you send me yours?
Best regards,
Jick

Try adding an attribute to the person_has_lenders table in your ERD, e.g., a date, as shown in my original diagram.
The class diagram and the generated file set will be different then, isn't it?

Jick
Thank you for this fix. There is more to this, however.
Have you tried to compile the project after this issue was fixed?
Personally, I could not compile it with 22 errors returned. All errors are related to one point: Methods are defined in the DAO objects of the Person and Person_has_lenders objects while the generated code assumes they are declared in the objects themselves.
For example, loadPersonByORMID is declared and implemented in PersonDAO and PersonDAOImpl correspondingly while the generated code attempts to call it via Person (see below).
Since this is just generated code, not a single line was added, I assume the generation procedure needs some more attention.
Could you look into it and advice? Thank you.
Best regards
Mikhail

Any hint why you have selected to restrict this? Just to understand the problem better...
Could you also provide a patch for Mac OS. Thank you.
