Hi !
a call to makePersistent on my Entity does just nothing. The call returns
the "saved" identity as expected, throwing no Exception. But the Entity is
not saved in the datastore.
I have many other Entity types that I persist the same way, with no
difficulties. what im I doing wring ???
Here's the method :
@Override
public Subscription createSubscriptionForContact(String updaterUserKey,
String contactKey) {
PersistenceManager pm=PMF.get().getPersistenceManager();
Subscription newSubscription;
try{
newSubscription = new Subscription(updaterUserKey);
newSubscription.setContactClientKey(contactKey);
newSubscription.setCreationDate(new Date());
newSubscription.setsubscriptionStatus(TRDS_CONST2.SUBSCRIPTION_STATUS_NEW
);
newSubscription.setLastUpdateDate(new Date());
newSubscription.setLastChangeByUserID(updaterUserKey);
newSubscription = pm.makePersistent(newSubscription);
//this throws a NullpointerException because the encoded String Key as not
been populated
System.out.println("Wrote object in the datastore. Key=" +
newSubscription.getKey().toString());
}
finally{
pm.close();
}
return newSubscription;
}
And here's the class :
@PersistenceCapable(detachable="true")
public class Subscription implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName="datanucleus", key="gae.encoded-pk", value="true")
private String Key;
//@Persistent
//@Extension(vendorName="datanucleus", key="gae.pk-id", value="true")
//private Long KeyId;
@Persistent
private Date dateRDV;
// Création/update du présent objet
@Persistent
private Date creationDate;
@Persistent
private Date lastUpdateDate;
@Persistent
private String lastChangeByUserID;
@Persistent
private String contactClientKey;
@Persistent
private String contactBillingKey;
etc...
public Subscription(){
totalAmount=new Long(0);
totalRDSRest=new Long(0);
totalGotBeforeJumpDate=new Long(0);
totalDueAmount=new Long(0);
totalAccount=new Long(0);
reductionGROUPValue=new Long(0);
bonCadeauPCFValue=new Long(0);
bonCadeauUBIValue=new Long(0);
bonCadeauGESValue=new Long(0);
reductionPAFValue=new Long(0);
reductionHEHValue=new Long(0);
reductionOTHERValue=new Long(0);
reductionTAJValue=new Long(0);
}
public Subscription(String lastChangeByUserId) {
Date now = new Date();
this.creationDate = now;
this.lastUpdateDate = now;
this.lastChangeByUserID=lastChangeByUserId;
}
//
// Calculation methods
//
//Updates totalDue and RDS rest regarding the state of the object.
public void calculateBilling(){
long totalDue = this.getTotalAmount()
+this.getBonCadeauPCFValue()
+this.getBonCadeauUBIValue()
+this.getBonCadeauGESValue()
+this.getReductionPAFValue()
+this.getReductionHEHValue()
+this.getReductionTAJValue()
+this.getReductionGROUPValue()
+this.getReductionOTHERValue();
this.setTotalDueAmount(totalDue);
long newRDSRest=totalDue-this.getTotalGotBeforeJumpDate();
this.setTotalRDSRest(newRDSRest);
}
public String getKey() {
return Key;
}
public void setKey(String key) {
this.Key = key;
}
public Date getDateRDV() {
return dateRDV;
}
public void setDateRDV(Date date) {
this.dateRDV = date;
}
public Date getCreationDate() {
return creationDate;
}
public void setCreationDate(Date creationDate) {
this.creationDate = creationDate;
}
public Date getLastUpdateDate() {
return lastUpdateDate;
}
public void setLastUpdateDate(Date lastUpdateDate) {
this.lastUpdateDate = lastUpdateDate;
}
etc...
}
Thank you for your help !!!
