Please could someone in-the-know check these steps to configure 1.3.5:

This sounds exactly right.
* write a bespoke command to do the view logic,
extending ActionCommand.java (is that correct?)
and reference it in the chain-config.xml in the
'process-view' chain
You don't *have* to extend ActionCommand, but by
doing so you save yourself the trouble of casting
the Context to an ActionContext.
By the way, the 'servlet-exception' chain from
struts-core has only 2 commands:
ExceptionHandler, PerformForward. But the chain
from struts-tiles.jar has 4: ExceptionHandler,
ExecuteForwardCommand, TilesPreProcessor,
PerformForward. Is that 'ExecuteForwardCommand'
tiles specific?
hm. No, ExecuteForwardCommand is not tiles
specific. I can't think of any reason off-hand
for the inconsistency, except for error.
applying per-forward commands is something new
that not many people have begun using, so I can
imagine that no one has contemplated whether they
should or should not be supported automatically
on exception-handling commands or not. In
general, I don't see why not, except that one
wants to keep exception handling processes as
simple as possible to minimize the risk of a
secondary error derailing the handling of the
original error.
