Creating ADF Databound Tables 4-15
4.
In the Edit Property dialog, expand the toolbar facet for the panelCollection component and then expand the toolbar that contains the Create command
component. Select that component and shuttle it to the Selected panel. Click OK. This sets that component to be the trigger that will cause the table to refresh.
5.
Create a button that allows the user to merge the new objects into the collection. From the Data Controls panel, drag the merge method associated with the
collection used to create the table, and drop it as a toolbar button or link into the toolbar.
Figure 4–8 shows merge method for the Suppliers collection.

4.4.2 What Happens When You Create an Input Table
When you use the create operation to create an input table, JDeveloper:
■
Creates an iterator binding for the collection, an action binding for the create operation, and attribute bindings for the table. The create operation is
responsible for creating the new row in the row set. If you created command buttons or links using the merge method, JDeveloper also creates an action
binding for that method.
■
Inserts code in the JSF page for the table for the ADF Faces components. Example 4–5
shows the page definition file for an input table created from the Supplier
collection some attributes were deleted in the Edit Columns dialog when the collection was dropped.
Example 4–5 Page Definition Code for an Input Table
executables variableIterator id=variables
iterator Binds=root RangeSize=25 DataControl=SessionEJBLocal id=SessionEJBLocalIterator
Tip: If you will want the user to be able to continue updating the
row after it is persisted, then you should create the button using the persist method instead. For more information, see
Section 3.6.3, What You May Need to Know About the Difference Between the Merge and
Persist Methods.

Example 4–6 shows the code added to the JSF page that provides partial page
rendering, using the Create Supplier and Commit New Suppliers command toolbar button as the triggers to refresh the table.
