Abstract
Techniques for determining and tracking dependent properties for a calculated property are provided. A request for a value of a first property is received. The value for the first property is calculated, including accessing values for one or more properties used to calculate the value for the first property. The accessing of the values for the one or more properties may be detected, and the one or more properties may be tracked as dependent properties for the first property in a first set of dependent properties. A change in the value of a second property may subsequently be detected. If the second property is determined to be included in the first set of dependent properties, the value of the first property is invalidated.
