Item class customization

This method is called each time an instance of this object is loaded from the database or initialized for a new item.

This is the perfect place to attach your event methods.

Very important: do not use any inefficient code or queries calling the database in this method. This would slow down every database load, and for example it would make every gridview targeting this content extremely slow.

Display text representing this item.

This text is used to represent the item in many occasions.

The default value is composed of the content-type display name and the reference.

Short display text representing this item.

This text is used to represent the item when the space is limited.

The default value is the reference.

Indicates whether comments are enabled for this item.

This allows to show or hide the comment icon in the form. A more global option exists in Designer.

Allows to customize default file names proposed to users for each template.

This method receives a list of customizable file names. Keys are template names, values are default names for instances.

This is the method called when an item is deleted.

By default, it only flags the row in the database.

Override this method to change or extend this behavior.

If an object is saved with an older version than the last persisted (in database), the system will try to merge the versions values (if no conflicts between values) and will then save the merged item to database.

This option is enabled by default and a more global option exists in Designer.

When enabled, this allows to modify an item while an user is editing it. If no conflict appears (by value) the two versions' values will be merged.

This method generates a message (subject and body) from a modeling message (ContentMessage).

Can be overriden to change the whole generation of messages.

This method gets the content of a message placeholder (in a ContentMessage) in the specified language.

Must be overriden when such placeholders have been designated in the model to provide their content.

Returns a reference for the current item.

Is called by the Save method when the item is not yet created and the reference is empty.

By default, the method ReferenceGenerator.GenerateReference is used.

Used to initialize a task title in the current workflow state.

By default returns the following pattern: "{Reference} : {State}".

Another possibility to override this title could be to override the Save method of the task object.

By default, computes the due date using modeling settings on current state and taken transition.

The method is called when new tasks are created for the workflow, generally when a new state is reached.

This method gets the list of users notified when comments are added to this item.

By default, the list contains users having already posted a comment, or present in a flagged field ("Users receive notifications for new comments" in the application model).

This method checks if a field is required before any Save of this item.

By default, returns True if the field is marked as required or if the transition requires this field, if a transition is specified.

Note : will return false for all FileHolder fields before creation.

Override this method if you want to force-open this item's visibility to every user having access to this Packflow site.

This property returns a technical text representing this object.

Used in logging or exception messages.

The default text contains the type, id, GUID, instance creation date and parent information.

Applies the data of this object in the database.

Override this method to extend the way an item is saved.

If multiple transitions are possible out of a state; the conflict must be resolved.

By default, takes top most transition based on Transition Priority and then on participation count.

Override this method to make your own rules of transition resolution.

Please note that this method is only called when the users' decision (via task) are not sufficient to determine the outbound transition.
