I tried to persist a class A with an array typed property. The array is of type B. When I construct an object of type A with instances of type B in its array property hibernate tries to update the collection instead of inserting it.
What do I wrong ?
Hibernate version:
3.2 alpha1
Class code:
Code:
package array;
public class A {
int id;
int version;
B[] ba;
public final B[] getBa() {
return ba;
}
public final void setBa(B[] ba) {
this.ba = ba;
}
public final int getId() {
return id;
}
public final void setId(int id) {
this.id = id;
}
public final int getVersion() {
return version;
}
public final void setVersion(int version) {
this.version = version;
}
}
Code:
package array;
public class B {
int id;
int version;
double value;
public final int getId() {
return id;
}
public final void setId(int id) {
this.id = id;
}
public final double getValue() {
return value;
}
public final void setValue(double value) {
this.value = value;
}
public final int getVersion() {
return version;
}
public final void setVersion(int version) {
this.version = version;
}
}
