Variable Overrides

Variable overrides enable you to override variable default values for composite components. They cannot be used for simple components.

When a component contains other components, called child components, variable settings only affect the top-level parent component. All child components use the default values for their variables. A child component can obtain variable values from its parent component in these two ways:

• The container (parent) component “pushes” variable values to the contained (child) components. To override the default values for child components, set the variable overrides when you create a component that contains child components. Each referenced component has a set of variable overrides that you can use.

• The contained (child) components “pull” variable values from the container (parent) component. One or more of the contained component's variable values are defined based on the value of a variable in the container component. The contained component uses the variable substitution syntax :[container:varname] in the default value of its variables.
