You can allocate an expression to the elements of the task container, which refers to an element of the method container.

You define this binding in the definition of a single-step task. It is only necessary if export parameters are defined for the object type method (only for synchronous methods). The binding from the method container to the task container is executed when a synchronous object method has been processed successfully.

The workflow system proposes this binding definition if you have specified an object method with parameters during definition of the single-step task. If new elements are required in the task container, proposals are also made for these. You can edit and confirm these proposals or reject them. For further information, refer to Rule-Based Proposal for Binding Definitions.

You can modify this binding definition. But this will usually only be necessary in exceptional situations.

The container elements _WI_Object_ID and _WI_Result of the task container are not incorporated into the binding definition between the method container and the task container.

At runtime, the system ensures the following:

• If an object was created for a method, the reference to the object created is entered in the container element _WI_Object_ID .

• The result (if applicable) of the method is entered in the container element _WI_Result .
