Which two steps are required to reference a typelist with a Typefilter?

Referring to a typelist with a Typefilter involves a specific process that ensures the correct mapping and filtering of the list within an entity.

The first step includes adding a typekey field to the entity. This typekey acts as a reference point that connects the entity to the typelist. Additionally, specifying the name of the filter in the typefilter attribute tells the system which subset of the typelist should be utilized based on defined conditions, effectively controlling the options available to users.

This approach aligns neatly with the principles of Guidewire's configuration system, where typekey fields are essential for linking entities to their corresponding typelists. By doing this, the system can leverage the filtering mechanism to provide a context-sensitive experience based on business rules, permissions, or other criteria.

In contrast, while creating a mapping for the typekey and defining its associated filter is a necessary aspect of working with typekeys, it is not one of the steps required to directly reference a typelist with a Typefilter in the context outlined in this question. Similarly, referencing the typelist directly in the entity declaration or including the typelist name in the entity attributes does not provide the targeted filtering of options that is achieved through the combination of a typekey field and a type
