/**
* Sets the PropertyStyle to use to inject a request-level '_this' attribute (the underscore is
* needed because 'this' is a reserved word in EL) into JSF evaluations.
*
* JSF EL expressions rely on the JSF context being properly initialized with certain managed
* bean names. This is rather brittle. Instead, injecting '_this' allows the EL to refer to the
* originating object (i.e. #{_this.name}) regardless of how the JSF context is
* configured.
*
* Note: injectThis cannot be used within attributes such as
* faces-lookup. Those attributes map to well-defined places within the JSF
* framework (i.e. f:selectItems) and are evaluated at a different phase of the JSF
* lifecycle. In some cases they will skip invoking FacesInspectionResultProcessor.
* For example if a h:selectOneMenu fails to validate during POSTback, its
* f:selectItems will be redisplayed without a new inspection and with no chance to
* injectThis.
