public class B2BRepositoryFormHandler
extends RepositoryFormHandler

This form handler extends RepositoryFormHandler to provide automatic management of relationships between existing repository items and repository items that are created and removed by this form handler.

For example, you can use this form handler to manage the relationship between organizations and billing addresses, automatically adding each a billing address that is created to a parent organization's list of billing addresses, and automatically removing that address from the parent organization's list when it is removed from the repository.

You use this form handler by configuring the repository id and item descriptor type of the parent item whose properties you want to manage, and configuring the name of the property you want to update when a repository item is created or deleted. This configuration is typically performed using hidden input fields in your jhtml pages, since each use of the form handler may affect a different parent item and a different property of that item.

The following properties will typically be set in a properties file

repository

This is the repository that contains items managed by this form handler

The following properties will typically be set in a jhtml file

updateRepositoryId

This is the repository id of the parent repository item whose properties are being updated as repository items are created and deleted.

updateItemDescriptorName

This is the item descriptory type of the parent repository item.

updatePropertyName

This is the property of the parent repository item that will be modified by adding (or removing) items created (or deleted) by this form handler.

updateKey

If a repository item is to be assigned to or removed from a map property of the parent repository item, updateKey identifies which map entry is to be modified.
