Documentation

Definition

The property "Singleton" specifies the number of instances that can exist in a dependent context node (that does not belong directly to the root node).

If the property "Singleton" is set, exactly one instance of the node exists. Its content changes when the lead selection of the parent node changes.

If the property "Singleton" is not set, one instance per parent instance exists. The content of the instances does not change when the lead selection of the parent changes.

Default:

• In Basis Release 7.00 up to and including Support Package 11:

  Yes (one runtime instance)

• In Basis Release 7.00 Support Package 12 and higher:

  No (one runtime instance per parent node)
