Examples of ptolemy.kernel.util.IllegalActionException

ptolemy.kernel.util.IllegalActionException
Thrown on an attempt to perform an action that would result in an inconsistent or contradictory data structure if it were allowed to complete.
Examples include:

An attempt to remove a port from an entity when the port does not belong to the entity.
An attempt to add an item with no name to a named list.
