> During invoke action phase we would like to retrieve a list of partial render IDs for some specific preprocessing (resetting submitted values for the case they're embedded in another form). Those IDs are normally available by {{PartialViewContext#getRenderIds()}}.
> {code}
> PartialViewContext partialViewContext = FacesContext.getCurrentInstance().getPartialViewContext();
> Collection<String> renderIds = partialViewContext.getRenderIds();
> {code}
> This works fine in combination with standard JSF components, such as {{<h:commandLink><f:ajax render="foo"/></h:commandLink>}} However, when a RichFaces/A4J command component is been used, such as {{<a4j:commandLink render="foo" />}}, an empty collection is been returned instead. Debugging learns that the {{ExtendedPartialViewContextImpl}} implementation stores them in {{componentRenderIds}} instead of {{renderIds}} and never returns it on {{getRenderIds()}} method. The {{ExtendedPartialViewContextImpl}} also doesn't seem to use {{renderIds}} in a sensible manner anywhere else.
> I believe that {{componentRenderIds}} really has to be {{renderIds}} instead.
> As far now, we workarounded this by accessing the {{componentRenderIds}} field using reflection.

> Collection<String> renderIds = partialViewContext.getRenderIds();

>     try {
>         Field componentRenderIds = ExtendedPartialViewContextImpl.class.getDeclaredField("componentRenderIds");
>         componentRenderIds.setAccessible(true);
>         renderIds = (Collection<String>) componentRenderIds.get(partialViewContext);
>     } catch (Exception e) {

> However, this introduced a nasty dependency in our code.
