About Supported Data Collection Operations in Oracle ADF

When you create and register business services for an application, the Data Control Palette displays two types of actions:

Actions that typically operate on all data collections in the current web page's binding context (such as commit and rollback) in the Operations folder at the root level of the hierarchy.
Operations on a specific data collection (for example, EmployeesView). Data collection&ndashspecific operations (such as create and delete) appear in the Operations folder as child nodes of the collection in the Data Control Palette.

Typical data control&ndashlevel, global actions defined by business services include:

Commit will commit a transaction that updates the values of data objects from the bound data collection to the database.
Rollback will rollback a transaction meant to update the values of data objects in the bound data collection. No data is sent to the database.

Typical data collection-specific operations defined by business services include:

Create will create a new data object in the bound data collection after the user submits the form with the response object. In the case of web applications, create is the default operation that appears on the Data Control Palette. Note: In the case of Java clients (JClient), dragging Create from the palette will set the button's action binding to CreateInsert (see below), as this is the preferred behavior for Java clients.
CreateInsert will create and insert a new data object into the bound data collection. This operation does not wait for the user to complete the submit. Note: This operation is available only with Oracle ADF Business Components and it does not appear on the Data Control Palette. In the case of web applications, to change an existing create-only operation, to a create-and-insert operation, display the action binding editor for the button in your UI Model and select CreateInsert. In the case of JClient applications, create and insert is the default behavior, although the Data Control Palette displays the operation as Create.
Delete will delete the current data object from the bound data collection.
Execute will execute the bound action defined by the data collection. In the case of a JavaBean, the execute operation will refresh the data control.
Find will retrieve a data object from the data collection.
First will navigate to the first data object in the data collection range.
Last will navigate to the last data object in the data collection range.
Next will navigate to the next data object in the data collection range. If the current range position is already on the last data object, then no action is performed.
Next Set will move the viewable range to the first data object after the current range position defined by the bound data collection. For example, when the data collection is a rowset, next set navigates to the first row after the current range position. If the current range position is already on the last set, then no action is performed. Note: This operation is available only with Oracle ADF Business Components.
Previous will navigate to the previous data object in the data collection range. If the current position is already on the first data object, then no action is performed.
Previous Set will move the viewable range to the data objects located just before the current range defined by the bound data collection. For example, when the data collection is a rowset, previous set navigates to the first row after the current range position. If the current range position is already on the last set, then no action is performed. Note: This operation is available only with Oracle ADF Business Components.
setCurrentRowWithKey(String) will pass the row key as a String converted from the value specified by the input field. The row key is used to set the currency of the data object in the bound data collection. When passing the key, the URL for the form will not display the row key value. You may use this operation when the data collection defines a multipart attribute key.
setCurrentRowWIthKeyValue(String) will pass the row key as a String specified by the input field. The row key is used to set the currency of the data object in the bound data collection. Use this operation only when the data collection uses a single key attribute and does not define a multipart attribute key. When passing the key as a value, the URL for the form will display the row key value.
