Run-time State
At run-time, an Object instance can have specific values for its attributes, or exist in a particular state. To model the varying behavior of Objects at run-time, use instance values selected from the 'Select <Item>' dialog and run-time states or run-states.
Typically there is interest in the run-time behavior of Objects that already have a classifier set. You can select from the classifier's attribute list and apply specific values for your Object instance. If the classifier has a child StateMachine, its States propagate to a list where the run-time state for the Object can be defined.
Example
This example defines run-time values for the listed variables, which are attributes of the AccountItem classifier for the instance.

Add run-time state instance variables to an Object
On the Properties window, or the '<object name> : Features' dialog the 'Run States' page lists any variables inherited from the classifier of the Object element. These inherited variables initially have no values and are inactive. You can activate and define a run state for them, or you can right-click on the '<object name> : Features' dialog and select the 'Hide Inherited Variables' option to hide them from view.
