Delete does not work for AdminPresentationCollection
Posted: Wed Oct 08, 2014 1:35 am
Hi,
I have created a custom entity Merchant. The business requirement is that a merchant can define its child merchants and a merchant can also define its parent merchant.
I have created following mapping in domain class
I see proper UI. I am also able to add child merchants using child merchants tab. But when I select a child merchant and delete it. It does not get deleted from list. As per requirements, we dont want to delete the merchant but the association should be removed.
I check BasicPersistenceModule.remove() method call, the item removed is successfully removed from list
I also see "saved" message on list but it does not get removed. Any idea how I can resolve this ?
Regards,

Code: Select all
@ManyToOne(targetEntity = MerchantImpl.class, optional = true)
@Cascade(value={org.hibernate.annotations.CascadeType.MERGE, org.hibernate.annotations.CascadeType.PERSIST, org.hibernate.annotations.CascadeType.SAVE_UPDATE})
@JoinColumn(name = "PARENT_MERCHANT_ID")
@AdminPresentation(friendlyName = "Parent Merchant", tab = "Merchant Information", fieldType = SupportedFieldType.FOREIGN_KEY,
validationConfigurations={
@ValidationConfiguration(validationImplementation="parentMerchantValidator",
configurationItems={
@ConfigurationItem(itemName=ConfigurationItem.ERROR_MESSAGE, itemValue="Parent can not be a child of other merchant")
})
})
@AdminPresentationToOneLookup(lookupDisplayProperty = "name")
private Merchant parentMerchant;
@OneToMany(fetch = FetchType.LAZY, targetEntity = MerchantImpl.class, mappedBy="parentMerchant")
@Cascade(value={org.hibernate.annotations.CascadeType.MERGE, org.hibernate.annotations.CascadeType.PERSIST, org.hibernate.annotations.CascadeType.SAVE_UPDATE})
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE, region="blStandardElements")
@BatchSize(size = 50)
@AdminPresentationCollection(friendlyName="Child Merchants", tab = "Child Merchants", tabOrder = 10, addType = AddMethodType.LOOKUP,
operationTypes = @AdminPresentationOperationTypes(removeType = OperationType.NONDESTRUCTIVEREMOVE))
protected List<Merchant> childMerchants = new ArrayList<Merchant>();

I check BasicPersistenceModule.remove() method call, the item removed is successfully removed from list
Code: Select all
if (SupportedFieldType.FOREIGN_KEY == ((BasicFieldMetadata) mergedProperties.get(originalPropertyName)).getFieldType()) {
String value = property.getValue();
Serializable foreignInstance = persistenceManager.getDynamicEntityDao().retrieve(Class.forName(foreignKey.getForeignKeyClass()), Long.valueOf(value));
Collection collection = (Collection) fieldManager.getFieldValue(foreignInstance, foreignKey.getOriginatingField());
collection.remove(instance);
break;
}
I also see "saved" message on list but it does not get removed. Any idea how I can resolve this ?
