If a business class doesn't implement
InternalMetadataStr, the ClassMetadata method will
duplicate the parent metadata whenever the method is
called, because the correct metadata instance will
never be found.

Johnny, há um pequeno problema quando se usa o caractere "(" para título das colunas do grid. O Press se atrapalha e acaba colocando aspas no começo da string que deveria ser usada como DisplayName e corta a string na posição do caractere ")".

Este não é um problema grave, dá pra ser tranquilamente contornado. Apenas abri esta issue pra deixar registrado.

Forte abraço.

FastReport, by default, saves user-defined variables
and the FR broker is re-creating such variables
without removing, or at least verifying if the

BulkRetrieve doesn't retrieve unloaded attributes (lazy loading) of proxies with an instance. Eg:

Session.BulkRetrieve(ProxyList, 0, Count, 'attr')

instances are skipped, because of that it doesn't retrieve the 'attr' field of instantiated objects.

Is it possible to access Objects involved in the MVP in a direct manner, thus I can formulate a complex query by code or manipulate items by code in an easy way and all this is reflected via MVP?

Create a data packet object which holds persistent data of a business object.

1. Lifetime

Starts with object retrieving or storage of a non persistent object (against a session) and finishes when the object is destroyed (notification event? direct event?)

1. Home

A data packet is a session object. TPressSessionPacket or TPressSessionObject are candidates to the name of the class.

1. Usage

Stores the persistent id and update count properties.

Stores the state of the object. The data packet need to know if the object wasn't changed, or if the change is relative or not.

An object that has a data packet object is a persistent one, otherwise (an object without a data packet) means the object wasn't persisted. A session is able to query the persistence state of an object.

The data packet also need to listen proxies and proxylists in order to instantiate class/id, or bulkretrieve on demand. When assigning a reference to a proxy, the session need to make a data packet to listen, or listen itself the proxy events in order to instantiate object(s) when necessary.

1. Cleanup of the Subject unit

Remove static public procedures, IPressSession interface, TPressObject.IsUpdated property, as well as PersistentId and UpdateCount params.

1. Refactor

InternalStore/Refresh/Dispose need to be refactored. An option is an interface that a BO implements in order to be notified of such events. Another option is use notification.

Translation of the article Metadata from english to portuguese-brazil.

Olá João, acho que encontrei um pequeno bug no PressObjects.

Para reproduzir a condição do problema, é fácil.

Basta criar uma classe, com pelo menos 1 atributo TPressCurrency e estar usando o PostgreSQL como servidor de banco de dados.

Inserir um registro novo e ao salvar, esta mensagem de erro aparece:

Preparation of query failed. (PostgreSQL: ERROR: column "cost" is of type numeric but expression is of type money
LINE 1: ...money,int,bigint) as update TEquipment set Cost = $1, Update...
^
HINT: You will need to rewrite or cast the expression.
).

Creio que seja um problema do framework, pois alterando o tipo do atributo pra TPressDouble, o problema sumiu.
Entretanto, ainda sou novato no PostgreSQL e não sei se falta configurar algum parâmetro que envolva campos numéricos usados para valores monetários.

Notifications raises AV exception after unassign
duplicated events. The
TPressNotificationList.RemoveNotification remove only
the first occurence, resulting some invalid pointers.

Converted from SourceForge issue 1523220, submitted by jcmoraisjr

An AV is raised whenever the framework look for a
Command instance, and there is at least one nil
pointer into de Command list.

Checking if the pointer is nil will fix this issue.

Using either GUIDs or DB-Generators will cause an exception on foreign key references for newly added Objects when they contain a TPressPart Attribute.

Solution: generate ID from bottom up, e.g. for a Person with an Address Part:

Generate the Persons ID prior to the Address ID

Whenever an invalid Proxy is assigned to a ProxyList,
eg, a Proxy referencing a class that isn't allowed to
that List, the framework raises an AV due to an object
destroyed inside the ProxyList notification.

Simply removing the try/except block solves the issue,
but might cause memory leakage.

Hello Morais.

I saw you've changed PressMessages.inc to fix charset issues with FPC, calling the PressEncodeString function.

That looks ok. But it's missing an update on resource string files. They're still on CP1252 codepage, and that's end on corrupted strings after the PressEncodeString function.

Can you verify this?

I've personally checked the PressMessages_ptbr.inc file.

Let me know, if I can help somehow.

Hello,
please find attached modified code in order to add :

• Mandatory property for an attribute
• Spell checking of attribute content via regular expression (virtual in attribute, implemented in TPressString)
• Validity check of TPressObject throught validity check of its attributes
• Error reporting on validity check by attributes and collecting on TPressObject

Hope this could be included in trunk

When a notification causes a notifier destruction the
next notifier isn't called, because after it's
destruction, the "next" will be the "current" item:

with CurrentItem.Notifiers.CreateIterator do
try
BeforeFirstItem;
// 2nd - skipping the current and not processed
while NextItem do
// 1st - removing the current notifier
CurrentItem.ProcessEvent(AEvent);
finally
Free;
