The app views used to be a part of ErlyWeb, but they were replaced by
components + 'phased' rendering. Unfortunately, those old tutorials
are still on my blog so I see where the confusion would come from :)

Do you want a different sidebar for every page, or the same sidebar
(but with dynamic contents)? If you want a different sidebar, you can
include it in your components directly, so each component could chose
which sidebar to include. If you want the same sidebar, include it in
the html_container (or the main_layout_container as in my previous
email).
I think you probably want the same sidebar, in which case I would
create a sidebar component and include it in main_layout_container
next to the requested component, e.g.:
sidebar_controller:
index(A) ->
{data, ...}.
sidebar_view:
<%@ index(Data) %>
<div id="sidebar">
<h1>sidebar</h1>
<% Data %>
</div>
main_layout_container_controller:
index(A, Ewc) ->
[{ewc, sidebar, [A]},
Ewc].
main_layout_container_view.et:
<%@ index([Sidebar, Data]) %>
<table>
<tr>
<td><% Sidebar %></td>
<td><% Data %></td>
</tr>
</table>
app_controller:
hook(A) ->
{phased,
{ewc, A},
fun(Ewc, Data, _PhasedVars) ->
{ewc, html_container, [A, {ewc_main_layout_container, [A, {data, Data}]}]}
end}

That one got me too. Now I use 'usr' :)
