Setting a row as non editable based on a value :In this ADF-Insider-Essentials you will see how you can set a row of data to be non editable depending on the value in another field or attribute.
ADF BC Model Driven LOV Switcher : In this ADF-Insider-Essentials you will learn a feature of model driven list-of-values where the LOV definition can be switched at runtime. This is usually triggered by data in a related view object-attribute.
Referencing a default value from an attribute in a different EO :In this ADF-Insider-Essentials you will learn how you can default an attribute's value with a value populated from a different entity-object. For example, an order item price is defaulted to the suggested wholesale price for the product.
Implementing a total : Often in an application you will want to display a sum or total of a particular attribute, for example the total salaries in a department. In this ADF Insider Essential you will see how you can implement using a Groovy expression.
Building a test client for testing ADF Business Components : Application Development Framework Business Components can be tested in the ADF Model Tester or in simple Test Client classes. These Test Client classes can work with generic view objects or set and use bind variables and view criteria. This ADF-Insider shows you how to write the class using a template and set all the appropriate component values.
Basing ADF Business Component View Objects on more than one Entity Object : Tables are littered with foreign keys that have little meaning to users. Often we want to show fields from other tables with more meaningful values to the user, and, if the user changes the foreign key then the lookup values are instantly changed. This presentation will show you how to create ADF Business Component View-Objects where the View Object is based on more than one Entity-Object: An updatable Entity-Object and a reference lookup Entity-Object.
Retrieving the previous value of an ADF BC attribute : Sometimes we will have a requirement to show the previous value of an ADF BC attribute, or even create a business rule that needs to compare an old and new value for an attribute. You will learn how easy it is to do this in this Application Development Framework(ADF) Insider Essential.
