> URL: https://issues.apache.org/jira/browse/MYFACES-2493
> Project: MyFaces Core

>
> This does not have any side effects but originally, FaceletViewHandler used
> this line on renderView method:
> // build view - but not if we're in "buildBeforeRestore"
> // land and we've already got a populated view. Note
> // that this optimizations breaks if there's a "c:if" in
> // the page that toggles as a result of request processing -
> // should that be handled? Or
> // is this optimization simply so minor that it should just
> // be trimmed altogether?
> if (!this.buildBeforeRestore ||
> viewToRender.getChildren().isEmpty())
> {
> this.buildView(context, viewToRender);
> }
> Since we need to solve MYFACES-2483 Find a way to allow c:if work with
> partial state saving enabled, we need a way to detect when a view is
> "updated", and check if UIViewRoot has children is ideal.
