Is the following an incorrect use of a!save(): a!save(local!variable, save!value)?

The use of a!save() is not erroneous in the context provided, as it follows the correct syntax and function of Appian's design standards. a!save() is utilized to facilitate the saving of values into local variables during the execution of an interface, such as when handling user input or managing state in a user interface component.

When you write a!save(local!variable, save!value), the first argument is the target variable (local!variable) where you wish to store the new value, and the second argument (save!value) is the value you want to assign to that variable. As long as both the local variable and the value are defined correctly within the context of the expression, this implementation is valid.

There are situations in which a!save() could be combined improperly with certain controls or expressions, or there could be conflicting data types, but as it stands, the interaction outlined is an appropriate use of the a!save() function. Understanding the syntax and structures used in Appian is essential for utilizing components like a!save() effectively within applications.
