> {{RichFunction}} provides number of utility functions for inlining JavaScript calls refering to client-side component API.
> Those functions (in fact utility methods) usually returns {{null}} when no such component found.

> This is not very clever, since developers might observe tough-times when refactoring or even authoring JSF pages - they will observe problems during testing or even worse in production.
> In case no such component found in tree, I propose to either:
> * throw exception
> * produce {{FacesMessage}} (this will be displayed just in Development mode)
