  • @MappedSuperclass
  • Important things on ID/UID
  • entity lives in three layers:
  • Flex client
  • JPA persistence context
  • database
  • When updating existing entities coming from the database
  • id is defined and is maintained in the three layers during the different serialization/persistence operations
  • when a new entity is being created in any of the two upper layers (Flex/JPA)
  • new entity has no id until it has been persisted to the database
  • most common solution is to
  • have a second persisted id, the uid
  • which is created by the client and persisted along with the entity
  • recommended approach to avoid any kind of subtle problems is to have a real uid property which will be persisted in the database but is not a primary key for efficiency concerns
  • You can now ask Tide to
  • limit the object graph before sending it
  • Flex with the following API :
  • EntityGraphUnintializer
  • uninitializeEntityGraph
  • Person object will be uninitialized
  • uperson contains
  • only the minimum of data
  • to correctly merge your changes in the server persistence context
  • Tide uses the
  • client data tracking
  • to determine which parts of the graph need to be sent
  • Calling the EntityGraphUninitializer manually is a bit tedious and ugly, so there is a cleaner possibility when you are using generated typesafe service proxies
  • annotate your service method arguments with @org.granite.tide.data.Lazy :
  • @Lazy
  • take care that you have added the [Lazy] annotation to your Flex metadata compilation configuration
  • in the Flex application, register the UninitializeArgumentPreprocessor component in Tide as follows :
  • [UninitializeArgumentPreprocessor]
  • all calls to PersonService.save() will
  • automatically use a properly uninitialized version
  • of the person argument.
  • 15.4. Dirty Checking and Conflict Handling
  • simplify the handling of data between Flex and Java EE
  • Chapter 15. Data Management
  • Tide maintains a client-side cache of entity instances and ensures that every instance is unique in the Flex client context
  •  uid().hashCode();
  • Tide currently only supports Integer or Long version fields, not timestamps and that the field must be nullable
  • in a multi-tier environment (@Version annotation)
  • highly recommended to use
  • JPA optimistic locking
  • highly recommended to add a
  • persistent uid field
  • AbstractEntity
  • in general this identifier will be
  • initialized from Flex
  • @Column(name="ENTITY_UID", unique=true, nullable=false, updatable=false, length=36)     private String uid;
  • @Version     private Integer version;
  • uid().equals(((AbstractEntity)o).uid())

  • to enable/disable a Save button
  • correct way of knowing if any object has been changed in the context, is to use the property meta_dirty of the Tide context

  • check that its @Version field has been incremented

  • Modes define what SQL syntax MySQL should support and what kind of data validation checks it should perform
  • Server SQL Modes
  • When working with InnoDB tables using the InnoDB Plugin, consider also the innodb_strict_mode configuration option. It enables additional error checks for InnoDB tables, as listed in InnoDB Strict Mode
  • ...7 more annotations...
  • Setting the SESSION variable affects only the current client. Any client can change its own session sql_mode value at any time
  • To avoid this, it is best to use single-row statements because these can be aborted without changing the table

  • cygwin permissions bug on Windows 8
  • Permissions 0660 for '/home/Vineet/.ssh/id_rsa' are too open. It is required that your private key files are NOT accessible by others. This private key will be ignored. bad permissions: ignore key: /home/Vineet/.ssh/id_rsa Permission denied (publickey).
  • quick fix is to change the group on all existing entries:
  • ...12 more annotations...
  • chgrp -R Users ~/.ssh
  • 1) Check the group Id of the ‘Users’ group in /etc/group
  • -rw-------
  • Here’s how you can fix the root cause:
  • chmod 600 ~/.ssh/id_rsa
  • cat /etc/group | egrep '^Users:' | cut -f3 -d':'
  • value was 545
  • 2) Check the primary group for your user in /etc/passwd
  • cat /etc/passwd | egrep '^Vineet:' | cut -f4 -d':'
  • value was 513 (which was the value for the ‘None’ group in /etc/group)
  • 3) Change this value to the one found in the previous step for ‘Users’ (545 in this example)
  • 4) Exit cygwin and restart

graniteds bean validation

shared by kuni katsuya on 06 Jun 12 - No Cached
  • "Bean Validation" specification (aka JSR-303) standardizes an annotation-based validation framework for Java
  • Flex doesn't provide by itself such framework. The standard way of processing validation is to use Validator subclasses and to bind each validator to each user input (see Validating data). This method is at least time consuming for the developer, source of inconsistancies between the client-side and the server-side validation processes, and source of redundancies in your MXML code.
  • GraniteDS introduces an ActionsScript3 implementation of the Bean Validation specification and provides code generation tools integration so that your Java constraint annotations are reproduced in your AS3 beans
  • ...16 more annotations...
  • GraniteDS validation framework provides a set of standard constraints
  • Constraint Description AssertFalse The annotated element must be false AssertTrue The annotated element must be true DecimalMax The annotated element must be a number whose value must be lower or equal to the specified maximum DecimalMin The annotated element must be a number whose value must be greater or equal to the specified minimum Digits The annotated element must be a number whithin accepted range Future The annotated element must be a date in the future Max The annotated element must be a number whose value must be lower or equal to the specified maximum Min The annotated element must be a number whose value must be greater or equal to the specified minimum NotNull The annotated element must not be null Null The annotated element must be null Past The annotated element must be a date in the past Pattern The annotated String must match the supplied regular expression Size The annotated element size must be between the specified boundaries (included)
  • Constraint annotations must be placed on public properties, either public variables or public accessors
  • -keep-as3-metadata+=AssertFalse,AssertTrue,DecimalMax,DecimalMin, Digits,Future,Max,Min,NotNull,Null,Past,Pattern,Size
  • must use
  • keep the constraint annotations in your compiled code
  • Error Messages and Localization
  • {name.notnull}
  • {name.minsize}
  • use the built-in ResourceBundle support offered by Flex:
  • to add support for different locales
  • follow the same principle:
  • create a ValidationMessages.properties for the new locale
  • translate all default error messages and add new ones for your customized message keys
  • Note that the bundle name must always be set to "ValidationMessages".
  • Using the FormValidator Class
