public class PBESelectedCondition

extends PBECondition

Description:

PBESelectedCondition returns $true if the specified row is the selected row of the object this event is declared on.

PBESelectedCondition can be used in object and attribute events.

Event String Action Name:

selected

Syntax:

selected( position )

Parameters

position - Position can either be "first", "last" or an absolute row number.

Examples:

 PBE:attributeEvent(
   "customers",
   "name",
   "after:find:fetch(first) if selected(0) set('This is the empty-record!', status)");
 

This event causes the first record after activation of the "find" method on object "customers" to be fetched. If the search did not find any records, the empty-record (index 0) would still be selected after fetch(first) and thus the attribute "status" would be set to "This is the empty-record!" to provide feedback to the user.
