public class MultiFileItem extends CanvasItem
The MultiFileItem provides an interface for a user to save one or more files that are related to a DataSource record, where each file is represented by a record in a related DataSource.

Use MultiFileItem when a record may have one or more files associated with it (such as attachments to an email message) where no information about the files needs to be stored other than the files themselves. If you have several fields associated with each file (such as an uploaded document with a version, comments and processes associated with it), consider instead an ordinary DataSource with on field of type "binary", and using the `FileItem` for upload.

See the `Uploading Files` overview for more information on upload.

DataSource Setup

In a relationship sometimes called a "master-detail" relationship, the MultiFileItem stores files in a "detail" DataSource which are related to a "master" DataSource record being edited by the form which contains the MultiFileItem.

To use a MultiFileItem:

- declare a "detail" DataSource to store the related files. At a minimum, this DataSource must have:
  - a `primaryKey` field
  - a field declaring a `foreignKey` relationship to the primaryKey of the "master" DataSource
  - a field of type "binary"
- `bind` a DynamicForm to the "master" DataSource
- in the DynamicForm bound to the "master" DataSource, declare a field with `editorType`:"MultiFileItem" and a `dataSource` property set to the ID of the "detail" DataSource

An example "detail" DataSource for storing files is shown below. This "detail" DataSource assumes a "master" DataSource with `DataSource.ID` "masterRecord" and with a primaryKey field "id".

        <DataSource ID="uploadedFiles" serverType="sql">
          <fields>
             <field name="fileId" type="sequence" primaryKey="true" hidden="true"/>
             <field name="masterRecordId" type="number" foreignKey="masterRecord.id" hidden="true"/>
             <field name="file" type="binary" title="File"/>
          </fields>
        </DataSource>

Aside from a single "binary" field, the "detail" DataSource should generally have only hidden fields, as shown above. Additional internal fields (such as a "lastUpdated" field) may be added, but will not be editable via MultiFileItem.

Display

The MultiFileItem appears as a list of files related to the current record. An optional button, the `removeButton` allows removing files. A second optional button, the `editButton`, launches a picker for uploading further files.

Saving

In all cases, uploading a new file is an "add" DSRequest against the `dataSource`.

The MultiFileItem has two modes, according to whether the "master" record is being newly created via an "add" operation or whether the master record is pre-existing ("update" operation).

If the master record is pre-existing, each file added by the user is uploaded as soon as the user exits the picker launched from the edit button, and the list of files shown in the main form reflects the actual list of stored files.

If the master record is being newly created, files are not actually uploaded until after the master record is confirmed saved, and the list of fields shown in the main form reflects files which will be uploaded after the master record is saved.

In both cases, if there are multiple files to upload, they are uploaded one at a time, as a series of separate "add" DSRequests against the `dataSource`.

Also in both cases, deletion of any file is immediate. In the case of a pre-existing master record, all files shown actually exist as DataSource records, and deletion is performed as a "remove" DSRequest against the `dataSource`.

  - ### setDefaultProperties

    public static void setDefaultProperties(MultiFileItem multiFileItemProperties)
    Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties of the class instance passed to this function. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

    Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

    Parameters:
      `multiFileItemProperties` - properties that should be used as new defaults when instances of this class are created
