• Write the code to reference a library program unit within an attached library in a form module trigger by using a variable.
• Identify the included reusable components in Form Builder.
• Create a calendar in a form module by using the Calendar object group in the Standard Object Library.
• Write the code to manipulate the calendar at run-time by using the Date_LOV.Get_Date built-in in the Calendar.pll attached library.
• Create a picklist in a form module by using the Picklist object group in the Standard Object Library.
• Display a populated picklist by using Form Builder built-ins.

Unit 4: New Features in Form Builder

• Identify the features available in Form Builder to handle possible errors.
• Identify the order of preference for the location of PL/SQL code.
• Identify the features of error messages caused by failed Form Builder calls to the Oracle Server.
• Match the predefined error messages with the DML declarative constraint violations that generate them.
• Complete the code for the ON-ERROR trigger to display error information caused by an implicit call to the Oracle Server.
