The spec (section 10.4.1.1) states that f:ajax execute/render ids are resolved
"The String value for identifiers specified for execute and render may be
specified as a search expression as outlined in the JavaDocs for
UIComponent.findComponent. The implementation must resolve these identifiers as
specified for UIComponent.findComponent."
1. There is no mention of this in the pdldocs for f:ajax.
2. An small sample illustrating this behavior would be extremely helpful.
Logging this issue to request that we address both #1 and #2 as spec clarifications.
