 String propertyName)
                                         throws IntrospectionException

Retrieves the default value of a specified property for a given component.

If the default values for the component's class have not been cached yet, this method invokes collectDefaultProperties to compute and cache them. Then, it attempts to retrieve the default value for the specified property name from the cache.

Parameters:

component - the UI component whose property's default value is being queried

propertyName - the name of the property to look up

Returns:

an Optional containing the default value of the property if available, or an empty Optional if the property is not found

Throws:

IntrospectionException - if an error occurs while introspecting the component to collect its default properties
