Mirror Items / Synchronized Items in Oracle Forms

In Oracle Forms, Mirror items or Synchronized items are achieved through the property called "Synchronize with Item property Description" and below are the property details

Synchronize with Item property Description

Specifies the name of the item from which the current item should derive its value. Setting this property synchronizes the values of the two items, so that they effectively mirror each other. When the end user or the application changes the value of either item, the value of the other item also changes.

Applies to all items except OLE containers Set Form Builder

Required/Optional: Optional 

Default: NULL

Usage Notes:

• In earlier releases, this property was called the Mirror Item property
• You can set Synchronize with Item for base table or control blocks. When Synchronize with Item is specified, the current item’s Base Table Item property is ignored, and the item derives its value from the mirror item specified, rather than from a column in the database.
• If you use the GET_ITEM_PROPERTY built-in to obtain a Base Table Item property, it will obtain the value from the mirror item specified.
• You can use mirror item to create more than one item in a block that display the same database column value. Synchronize with Item restrictions
• The maximum number of items in a form that can point to the same mirror item is 100.
