Hi John, here are some more point mention in the New feature document
<extract start>
ADF Databinding
Sparse Bean Data Controls and Data Control Enhancements
When working with data controls, creating an XML file for each accessor in your data control is now optional. For example, your EJB data control may contain accessors for the Department and Employee entity beans, but you do not have to create XML files for these beans until you start modifying data control properties (for example, control hints).
If you do choose to create a bean XML file, you can use many of the ADF BC features in your data control. For example, you can choose which columns to display in the list of attributes. You can also add groovy expressions and a search form to your data control.
<extract end>
exactly i want to use the property like control hints and validation and all, but here the document not having details like "how to choose to create a bean xml file " option
thanks
