Using Standard Control Data

Standard control data is not defined explicitly as input or output for a method.

Controlling attributes (either standard or specific controlling attributes) are not passed on as parameters for hooks. Instead, control data can be used through the getControlAttribute() helper method. Refer to section Assisting Functions.

It is not possible to update standard control data from the input in a hook.

Note: For LN, controlling attributes cannot be used as method arguments. Consequently, controlling attributes also cannot be output for a method implementation. Controlling attributes cannot be set.

Exception is when using specific methods having processing order ‘batch’, because then you must build up the whole response in the on execute hook.

See Hooks for Batch Methods.

In that case note however that the control area is used for the request/response as a whole, so no controlling attributes can be determined per object instance.
