Property :: initializedInstance - Is instance initialized instance
When the instance has been provided with the initializeInstance() function the instance has not yet been created and access is limited for subordinated property handles. The property returns whether the selected instance in the property handle is an initialized instance (true) or not (false).
When no instance is selected, the property returns false. When the property handle is not valid, the property throws an exception.
Return value: Success ( bool )
The value is true when the function was executed successfully. Otherwise the value is set to false.
