> Key: MYFACES-658
> URL: http://issues.apache.org/jira/browse/MYFACES-658
> Project: MyFaces
> Type: Improvement
> Components: Implementation

> I have written a ForEach component that is aimed to mirror jstl forEach
> capabilities. It works for pretty much all nested components, but
> specifically not for any SelectOne, SelectMany, ...
> There are (as far as I can tell) 2 major reasons for this:
> 1. The renderer (HtmlMenuRendererBase) renders the menu only in its
> encodeEnd, and it means that any attempt to encode children (forEach) is
> foiled as the call is never delegated. Really, the menu should be encoded in
> the encodeChildren method (if only for consistency).
> 2. and this one is linked to the above: The menu is rendered outside of the
> normal cycle. By this I mean that the menu renders itself and any children.
> Ideally, the menu would render only the <select></select> frame (encodeBegin
> and encodeEnd) and leave the selectItem creation to a separate renderer. This
> would allow me (in this case) to let my forEach renderer take care of child
> creation.
> Existing code can be easily reused as HtmlRendererUtils.internalRenderSelect
> renders SelectItemS perfectly without the need for the containing menu to be
> visible (except maybe for ID creation)
> Unfortunately I do not know what impact this kind of change may have on the
> rest of the lifecycle, but my guess is 'none', since only the encoding will
> differ and the ForEach component (or similar flow control) would not render
> visibly and does not have an ID.
